Limited by pelvic bones?

I've been attempting to get over the 3.25 inch diameter mark. Specifically I want to take the largest of the Huse Anal Dilator large set. It is 3.4" at the widest area of the top, then it drops to a 3" wide neck. It has been a little bit of a challenge due to more than just stretching being a factor. I feel like the limiting factor is my pelvic bones. After time trying to work it in I get to the point where I feel like I'm constantly at the edge of it slipping in. I'm wondering if there are any recommendations people who have surpassed such a challenge have for positions, lubricants, etc. Currently I have been using a high quality long lasting water based lubricant in addition to Liquid Silk. I've also considered trying an oil based and silicone based lubricant on my next attempt. So far I've been positioning myself above the toy and letting myself lower myself down on it using my weight. I have tried push and relax my pelvic floor muscles as if I were pushing out an enema or my other huge toys. It feels like more than muscles are limiting me though. I really want to feel the sustained stretch of the 3" neck. FYI, I posted pics of my largest toys if you are interested to see what I've done so far.

I'd recommend something a little more flexible than a hard acrylic dilator. Check out the GoldDreams line at bigsextoystore.com, they have a huge selection of sizes and shapes. 3.5 is about the biggest hard object I've ever managed, and it is really about finding the perfect angle for it to go in.

I have the same issue. The opening in my pelvis is not wide enough to get past a certain width. If that is your problem, you could get something stuck if it does somehow slip past the pelvic bone, and you aren't able to pull it out. Since the opening of your pelvis is longer from front to back, you may want to start looking for toys that are around 3" wide and more oval in shape.

Good question and great answers so far. I have no real answer other then to "confirm" some of the given answers with my experience.

I can handle the American bombshell small shellshock which is 3.1 inch diameter or 9.6 inch circumference all the way from top to bottom the same size.

I can handle the American bombshell bunker buster which is 3.2 inch diameter or 9.8 inch circumference at the widest top edge, and 2.9 inch diameter or 9.1 inch at the shaft.

These are soft material. I also have a normal shaped butt plug with a 2.9 inch diameter or 9.1 inch circumference. This one is half way between soft and hard.

The toys mentioned will fit great and are inserted easily, when my butt is gradually opened up first with a smaller toy and with using lube.

Now I do have the Ace of Spades which is 3.1 inch diameter or 9.6 inch in circumference. This one is made from a hard material and for the love of it I can not get this one in, tried different angles and positions, being as horny and lubed up as I can, being warmed up (toys and room temperature), but nope... I can't get it in yet.

So I can only confirm that the hardness of the material, and perhaps it shape play a big part here.

When a woman's cervix is fully dialated for birth, it is 10 cm =4", so I would think that most women would be able to take something approaching that in their butts, too. I have no idea of what the measurement of a man's pelvis is, so you will just have to find out what works for you.

Just keep at it, you'll stretch eventually. It took me a long time to get my Ace of Spades inserted the first time but now I can pop it in with no problem at all.

Obviously at some point we are all going to hit our limit but it doesn't sound like you've reached yours yet.

It's all here...

I had the huse anal stretching rings and they were great. Worked my way up to the largest of those and the thing about them were they weren't long at all. You had to be very loose to get the largest one in. They didn't like to stay put very well either.

How do the dilators compare? I've been wanting them for a long time and might pull the trigger on the large set if they stay inside. Also have you ever had them go all the way in past the base? I know they also sell a harness.

As far as limited by pelvic bone? I think everyone's different. Before I got rid of it I took http://www.extremerestraints.com/butt-plugs_1/the-three-bumps-for-your-rump-butt-plug_1901.html

The large all the way to the base.

I am a male and i have the ace of spades buttplug but i can't get it in. It feels like it is me pelvis stopping it from going in because my ass stretching isn't a problem. How can i get it in if its my bones are stopping it from going in.

The ace of spades is very firm and more difficult than softer toys of the same size.

So you can try other plugs, the B-51 is a nice one, bigger but it was easier for me.
