I have fun without touching it a few times, but only once while having my bottom pounded. But...several times with a former male friend, I had an internal orgasm from anal sex. I am guessing it is similar to what a female feels. There was no ejaculation during these intense feelings, just felt like I was going to explore. My bottom became all quivery, and I experienced spasms. Maybe it was me wishing it to happen, but he is the only man to ever make that happen. It felt wonderful!!!! Wish I had one more time with him!
