Eric,
I took down all the albums when I got an indication that this and several other accounts had been hacked. One of the albums that contained images of the latex balloon nozzle was removed at the time and I haven't uploaded those images since I took them down. You are correct that the most recent images in my albums are the clear silicone double balloon nozzles.
The clear silicone nozzles have larger balloons and a longer reach/depth than the natural latex rubber ones I have. They are also have a different feel.
Part of that is due to their larger size, of course. I sense that the latex balloons are more pliable in my rectum than the silicone ones. Both types seal well and both types normally stimulate me to a strong erection and eventual orgasm. But, I do have to be careful with the latex rubber ones because strong muscle contractions with a full colon of an enema solution are amble to push the catheter out. I could try to inflate the distal balloon more, but that only damages the balloon and shortens its life.
As I have noted a number of times, the key to using these types of balloons is to properly seat them and have them effectively seal the rectum. I know that is accomplished when I inflate the outer balloon and I feel it drawn up tightly against the outer anal sphincter muscles without it dislodging from the "grip" of the rectal muscle walls.
I do have two types of clear silicone double balloon nozzles. The ones with the inflator bulbs that have chrome-plated twist to open valves are my preferred type. I have purchased them via eBay and they have been somewhat more expensive than the other version. The other version has larger inflation bulbs with plastic push-to-vent valves. These two catheters look similar. However, they have slightly different dimensions including length and distance between the balloons. Again, properly seated in the rectum, both work well for me. The only drawback I've seen between the two styles is the leakage that can occur from the valve stem of the plastic valves. I've handled this by running a bead of glue at the junction of the valve body and valve stem and that seems to fix the problem. The model with the plastic valves is the one most commonly sold at various outlets. I have purchased mine via Amazon.
One more thing about those clear silicone nozzles. The advertise very large balloon volumes. They are unrealistically large and I suggest they are the burst volume and not the practical inflation volume. All elastomers have a practical stretch limit beyond which the elastomer is damaged and then forms a weak point for the eventual failure of the balloon. It's more difficult to visibly spot that type of damage on the fluted silicone balloon and much easier to see on the latex rubber balloon. Once the balloon is inflated enough to expand the fluted surface so that it present a smooth surface at the point of maximum diameter, there isn't much good that can come from continued inflation beyond that. One reason why my balloon nozzles have lasted so long is that I know the maximum inflation point by observing the balloon inflation behavior outside of my body and then not going beyond that.
