Anal Sex on top (squatting)???

Has anyone ever had butt sex in the riding position? Like you're on top. I just to have butt sex with my bf all the time and most of the time it hurts and it takes a while for it to start to feel good. So I was chatting with one of my friends and she said that she gets on top and have anal sex that way and she said it goes right in in that position. Has anyone ever tried anal sex like this? Or if anyone knows some positions of anal that make it feel better other than doggy style or from the back.
