So I have recently started seeing someone new and he is a little over 9 inches. I have never been with anyone bigger than 7 1/2 so this was really fun. Something happened though that I hadn't experienced with my previous times where I was in the position where he is laying down and I am simply sitting on top of him with my back towards him. After a few minutes in that position I was getting these intense feelings in my dick and precum was coming out and I was just waiting to cum, yet nothing happened. Was that the start of having an orgasm without using my hands? If so, is this how everyone else feels before it and how long do you need to keep it up to actually cum?
