I just finished a great session, with similar results as my last post.
I also learned something new; while I knew once the involuntary contractions started, I only found them pleasurable while being pulled in. I tried to focus and found I can find pleasure in the outstroke. In particular the feeling of pre-cum draining from the end of penis down onto the towel and following the surge from my prostate down the utrethra outward. Great stuff.
Well Buster I'm going to be taking your advice after this, I'm not going to stroke off, even though its rather tempting. I'm not sure if I'll have time for another session in the morning, I'm off work but I have a golf game to play and then I'll be gaming at a LAN party that night.
Who knows, maybe the conservation of the sexual energy will improve both my golf and video game skills
