The surgeon who performed my SRS was really, really good at preserving nerve endings, I truly believe that I'm every bit as sensitive after the surgery then I was before. As a result of this dilating at first it was incredibly painful, months went by of having to literally torture myself several times a day by using the stents so that I wouldn't close up down there resulting in another expensive surgery.
I fixed the problem by reshaping some of the stents from a rounded tip to a more bullet like shape and putting a layer of gel lubrication on the stent first and then cover that with liquid lube which resulted in a lot less pain and friction.
It's been a couple of years now and everything's fine and I can even ride a bike over long distances. The only bad thing I have to face is ignorance and how truly stupid some people are willing to act. Oh yeah, you know when a woman laughs really hard at something and she says I'm going to wet my pants and you would think oh how cute, well it's not.
