SiliconeNozzles Model B users: firmness recommendations?

@moliere, I agree that a Model B inserted too fast is unlikely to cause damage to a healthy person. I've got the firmest one, 12 Mildly Firm, which would be the most potentially dangerous silicone grade.

I'm a lot more careful now with my own insertions after two frightening experiences. Two times I had my Model B inserted about halfway when it hit a point of resistance and I impatiently continued to push against it instead of backing off as I knew I should do. As I unwisely continued to push against the resistance, I felt a sudden popping sensation inside me and I thought I heard an audible pop. At the same instant, I felt the insertion resistance suddenly drop to near zero as my Model B plunged the rest of the way in. The sensation was painless, slightly uncomfortable, and totally terrifying. I though for a minute that I had punctured or badly torn up something inside me. Both times that I did this to myself, I immediately pulled my Model B out to examine it and and examine myself for blood. I was relieved that I found none. After a minute on both occasions, I decided to try the insertion again to reassure myself that I was OK. I was easily able to do multiple insertions after both incidents. Soon these insertions started giving me that intense, orgasm inducing pleasure that we Model B fans know and love, and I knew I would be fine. These experiences lead me to believe that the Model B is pretty safe even when misused.

@Debgurl, my scary popping sensation experiences tell me you are exactly right about your hubby or any partner inserting a Model B for you. You wouldn't want let anyone do that without instructions before and during the process. The person being inserted has to be in control.

@Debgurl, you and your hubby are both so lucky now that you both enjoy doing Model B insertions for each other. 😄 I'm happy for both of you, but also envious. I so wish that Pam and I could do that together. I know she would insert my Model B for me if I begged her to, but she would never want to try it herself, and she thinks I'm crazy to want to play with long anal toys at all. I think I'll have to be content with her inserting me with butt plugs, 8-inch dildos, and more conventional nozzles.

Here's a question. If someone who has never experienced a Model B insertion before (or another beyond the rectum insertion) and wants to have that experience, is it better to learn solo, or have the help of an experienced partner doing the insertion for you? I'm not sure.

I'm also not sure exactly what caused my frightening popping sensations when using my Model B, but I have a theory. I think my Model B's skinny tip on top of its upper bulb got caught on some structure inside me. As I continued to push when I should have backed off, the structure bent the tip sideways as the bulb pushed past the structure. This possibly bent or stretched the structure too. When I pushed my Model B deep enough, the tip cleared the structure and it (and possibly the structure too) suddenly popped back into original position(s). Whatever happened, I know I don't want to do it again.

I've had things hang up on either the puborectalis (the "sling" that goes around the rectum) or the valves of Houston sometimes. Those can both be managed through positioning and focused relaxation. The puborectalis will tend to be a bit more uncomfortable if you push past it.

What is the current consensus on how transit between the sigmoid and rectum is controlled?

After all the discussion on the Model B, I decided the price is right and it's time to purchase this nozzle.

I'm with @moliere on this. At somewhere beyond 6-7 inches (15-17 cm) there is a point of resistance that I've experienced. I can feel it with my one-inch tube most distinctly...that the tube end "catches" on something before moving in. My larger tubes (1.6 inch diameter) and nozzles (more than 2-inches) also have to expand and push by this point of resistance. Once beyond this point, most resistance drops dramatically.

I suspect it is the navigation past these "rigid" structures in the rectum that the lead retention ball is being guided past.

I have a similar and perhaps more dramatic experience with a set of anal balls (I wouldn't call them anal beads). At 2.5 inches in diameter, it is an interesting experience as each ball passes this point and the rectum settles around each ball as they are inserted.

Cool :-) hopefully you don't have to wait very long before you receive it!

My new model B ball seal silicone nozzle just arrived and am getting excited for my first trial run. Would like to hear comments and suggestions from those currently using this nozzle and how they like it!

Model B Mildly firm update: Still courting. I came the closest to full insertion last night, but became nauseous as I attempted the last inch. I ended my session for the night with no sustained discomfort or nausea. I appreciate all the specifics given in this thread. I am excited to see what happens next.

Update -

Played with the newly arrived Model B this morning, using it solo to get the feel of it. As an anal toy, it goes in easy up to the last ball. Feels really good when I exercise with it in to that point. Really stimulates everything in the anal canal as the balls keep it secure while it massages. Will try it soon as a nozzle - can’t get any better!

I just ordered a model B last week. I got semi soft. According to their page, it will be a month or longer before it gets to me. Anxiously awaiting.

@trouble63 hopefully you'll get it sooner! Would love to read your first experience wit the semisoft modelB.

Model B update: Having a lot more success inserting this guy, here is the process I use. First, a 2 1/2 qt. soapsuds (1 tbls. bronners) enema, which is a high volume enema for me. Second, a water enema between 2 1/2 and 3 qt. rinse enema. Now for the third one, i use the Model B with 2 1/2 -3 qt. either water or saline. Use lots of lube, both in rectum and on nozzle and insert to the last ball--take your time. Then run in maybe a cup of so of solution, and with gentle pressure and some rotation, the Model B will pop in. Now you are ready for the rest of the enema, and it feels wonderful, usually i can get almost 3 qts in.

@trw428, congratulations! Your "ritual" is very similar to mine and successful insertion of the Model B is almost guaranteed! It's not a nozzle to use on the initial enema...but for the second or third it is wonderful!

And you're right...it feels good, too!

Have fun and play safe!

Deb

If you want to use it for a first enema you just slip only the first bulb in 😄

@debgurl Thanks, actually it was based on some of your posts that i bought the Model B in the first place. I think it is a great nozzle, well designed, just takes a good technique to get it to fit.

My Model B arrived just before I departed on a trip. Still in the unopened box in the back of the car. I may have to wait until I get home to open the box.

@trouble63 I'm wondering if you've already received your model B, since you ordered it about a month ago!

Mine took 30 days to arrive.

Initial Impressions

I can understand why people really enjoy this nozzle. First, it's a really nice length...long enough to slip all the way up through the rectum and just enter into the Sigmoid colon without protruding too far in. The narrow tip helps guide it through.

Second, the first or lead retention bulb is nicely sized. It's not so large that the bulb can't work its way past the sphincter muscles. For those not experienced with size (diameter), it can be a challenge. Of course, you have to get this lead bulb all the way up your rectum in order to get the retention bulb inserted.

I didn't have any issues getting this nozzle all the way inserted. It was nicely snug and seated nicely. I left it in for about 20 minutes without it attached to a hose or a bag. That cums next.

For the record, my Model B is a translucent nozzle made with a firmness of #18. The nozzle is flexible enough over its length but the retention balls do not flex or compress very much. If you are a virgin in this diameter range well up into your rectum, this firmness might be uncomfortable. If you know how to allow the muscles relax as you slide something this size into you, you will be able to handle this firmness level. A little softer selection might allow the retention ball to compress slightly and adjust its shape to fit, but you still have to deal with the volume of the retention ball even as it compresses. For me, I enjoy the firmness and the translucent color. When fully inserted, it has a very pleasant filling feeling. The lower retention ball could be larger (for me), but the sensation of having the retention ball held higher in the rectum is quite pleasant.

So, the next question is "How is the enema?" Well, I took a 3.5 liter baking soda enema with this nozzle. It feels different to have most of the liquid delivered directly above the rectum. It also feels like the stream from the end of the nozzle impinges on the turn of the Sigmoid, a very nice feeling. Although the nozzle is easy to hold in, for me, it took very little effort to push the nozzle out.

My initial reaction is that it is easy to understand why some people really enjoy this nozzle. It's a nice combination of sensations. YMMV!

Time to drain the rest of the enema out of me.

Mmmm sounds very nice! Could you post a picture of your nozzle? Haven't seen one in translucent silicone yet :-D

@EnemaRunner, I'm glad you enjoyed your initial enema with the Model B. Mine is in the #10 softness and the initial bulb is quite "squishy" and conforms to my anatomy quite well. I was afraid the #18 would be too unforgiving and your post seems to bear that out.

Thanks for the "test drive" report!!

Deb

@DutchGhost,

Pictures now posted in a new album.

One more thing wrt the nozzle...when the valve is fully open it fills me really fast. Probably faster than any other nozzle I have. There's quite a stream flowing out of it and it's not surprising I can feel it impinging on my colon.

A couple of observations with all of the past-the -rectum nozzles. I have a model B and a GRB75-16, when properly fitted, both are in the sigmoid. I can get more solution in with less urge with either nozzle than, say, a double balloon catheter. also, the initial expulsion is delayed a little and it seems to take longer to completely empty out. How does this fit with others experience?

I agree that both are in the sigmoid. I suspect that the Model B is just above the transition from the rectum to sigmoid because it likes to slide back down slightly to settle/seat on the "top" of the narrower rectum. I know I have a "long sigmoid" and the 17.5 inch long Grub nozzle that I have is just at the point of making the turn at the top of the sigmoid. My experience (so far) is that I hold about the same amount of enema solution with the Model B as with an other retention nozzle that doesn't take up a lot of volume (e.g., the CT122-32 fills a lot of my colon with tube which is space that cannot be filled with an enema solution). My double balloon nozzles, and even my single chamber inflatable, all allow me to hold about the same amount (more than 3-liters, usually 3.2-3.6 liters, and sometimes just north of 4-liters). I haven't noticed any real difference in hold time as that seems more related to the enema solution characteristics and the total volume.

I do like the #18 mildly firm model, however.

Finally got the GRB75-16 all the way in, takes a lot of practice, clean colon, enough lube, but it was worth it. 3 quarts is a huge enema for me, but even with this big nozzle in me , the 3 quart enema was not that tough to take, took a while for it to leave. Both this guy and the model B take some time and practice to fully insert, but it's really worth the effort, either as a stand alone toy, or a great nozzle for an enema.

I bought a Model B in September. It has taken some effort to get it to go in. I can spend as much as 5 minutes playing around trying to get it to go because it is not as rigid as it needs to be. Part of the problem may be that I got the softest model and I think that a firmer one would go in more easily. Even so, I use it most sessions.

Definitely justifies my use of the acronym YMMV (your mileage may vary). My Model B popped right in for me and it is #18 firmness. OTOH, the DBLBL-3XL was a bit more of a challenge (also #18 firmness). My softer nozzles are the longer and or larger nozzles.

I got the #10 too. You can't hold it at the end and slide it in, but if you grab right under the first bump it goes in OK. Then you can slide it in from the second ball or the end.

I like the way it easily follows the rectum and curve to the sigmoid. For me it's worth the slight inconvenience (which isn't really much).

Moliere---That is more or less my experience, too. Thanks for confirming it.

My is #10 as well, i think is just fine. It did take a while to be able to insert to the full, but once you have it, like riding a bike.

One of the things I learned at the outset was that my #10 firmness Model B could not be inserted by pushing it inside me from the end. A firm grasp in the middle (where the little ridges are located) helps me get the initial bulge inside, then the rest is easy. And I, too, love the way the nozzle conforms to my anatomy and follows the bend at the top of my rectum into the sigmoid. That feeling is simply divine!!

Deb

Debgurl is absolutely correct, the model B feels fantastic. It took me awhile to be able to insert it all the way, but with a little practice and a bunch of lube, it's the one to go to!! i use a soap-bisacodyl enema (look @ all threads on this subject), to start with, it's a great enema to flush out a lot , then a larger water enema, using the model B, cleans out the system very well. That's what i do the majority of the time.
