Hello everyone, sure looks like a very knowledgeable community here to learn along with. I'm ready to get myself a Bathmate X30, been reading up on it quite a bit discovering what's best, and considering a few accessories as well to enhance the experience. One item I saw mentioned in an old thread was using a pump donut ring seal over the gaiter to improve sealing and comfort as well as avoiding pubic discomfort when pumping . Also helps avoid getting the boys drawn in OUCH! I do understand the comfort seal is included, but inside diameter might allow your nuts to be pulled in under suction. Is it OK to use a silicon pump seal donut with the Bathmate? Or does another material work best? Is there any compatibility issue between silicone and the gaiter material? My concern is that the silicone might react or cause the gaiter rubber to degrade or soften and ruin it. With the large cost of the Bathmate, I for sure don't want to screw it up and damage it. I know from past experience that silicone toys must be kept apart when storing or they can melt each other, and silicone lube can damage them as well. Weird isn't it?! How large is the outside diameter of the gaiter on the X30? I see the sealing rings come in a few sizes, and there's some universal ones. Want to get a decent one which will last a while. The better-looking silicone ones are around $10-11 each. I'll be taking it slow and easy, and I think this might prevent frustration with keeping a snug seal so you don't have to jam it down hard to pump out the water . The Vac U Vin pump mod looks awesome too and would be another great finishing touch to build more vacuum as I progress further. Looking forward to happy gains!
