This is a serious question. I have never had sex with a man nor do I want to. But I wonder how it works. If a man penetrates your anus with his penis, does it touch your prostate? Is there excitement gotten from that or not? I have tried to use my wife's penis shaped vibrator to hit my prostate. And I had no luck. I couldn't get it in more than two inches or so, and it is substantially smaller around than I am. I don't know how you guys do it. Too much pain for me. Vaginas are just more more elastic.
