Anal orgasm

I was always fascinated the way women have orgasm. It's very different from a men's orgasm which is really short. So when I started cross dressing and playing transvestite, I kept on thinking how to improve my orgasms. I started to have an anal intercourse as a passive partner with other men, it was a bit painful, than I started to like it more and more and finally I realized that I can come with my sperm only because of other man penis is exploring my ass hole deeply, and I even don't masturbate myself anymore when having anal sex with other man and I come so strongly and this type of orgasm is twice or three times more powerful than a normal one and lasts longer. I think it's closer to woman's one. I really love it and lucky that I can get it sometimes. When I come like this my cock jerks, but the liquid which comes out is less thick than sperm.
