I don't know what I injured. But one nite I was riding and grinding on my 7" dildo really hard. The next morning when I took a shit, one of my turds had blood on the tip. Like it was dipped in blood about 1/2 inch. It never happened again, and I didn't feel injured in any way. I still wonder where the blood came from.
You don't say if you're M or F, but if your partner is gentle there should not be any injuries. I'm M and never been with another M human, but had always let this shetland pony screw me. He always stroked easy, but I had to watch when he got ready to shoot his load. One day I let this new shetland stud take me, he put it in easy enough, but then got rammy as hell with me. I got off balance a little and he hunched it in a little too far, I didn't feel any pain to speak of, but a while later I did pass some blood. I think he must have broken a small blood vessel, that was the only time it happened.
I'm a female and I love anal sex. The first time, it really hurt, but after that, I learned to relax and the feeling is awesome!
Does it by itself cause you to orgasm or must you have other stimulation at the same time to get there?
