I've always been very non-sexual and remain that way. When I had my nullification I requested 100% of the erectile tissue to be removed and I believe it was as I requested. I still have some muscle contractions during arousal, that I hate, and I believe it's related to the pelvic floor muscle. Now that I'm pursuing incontinence and possibly surgery for that, I am continuing to weaken the pelvic floor to see if I can get 'more bang for the buck'. I do still have the prostate but I'm not sure that does much for me anymore. Perhaps it's just time to take it all out. It does remove additional cancer risks as well.
So I guess you could say I've had the ultimate penis reduction, hehe. With my reroute, I can take a 30fr catheter now. It's snug but fits with little discomfort.
