Since my early teens I have been purposely peeing in my pants (underwear) as the prelude to my masturbating. Typically (and always in private) I'll lie on a towel or two and just pee right in my underwear. I will occasionally also wear my pajama bottoms or even jeans which helps with the excess pee. I get instantly and very aroused using this method. If I'm wearing pants I'll take them off and while pulling up on my underwear waistband (in the front) I rub myself through the wet material. This always results in a very intense orgasm. The warm wetness is intoxicating! My wife and I do enjoy a healthy sex life. She is aware of this technique and finds it erotic and is fascinated by the uniqueness. She is aslo curious how I came about this 'technique' which I myself do not have an answer! On a rare occasion I will do it in front of her. Though, I do prefer complete privacy. Different I guess...but don't knock it until you've tried it!!
