That's where a mans g-spot is. Most men will never experience it, because they do think it is a gay thing. I look at it as a sensationsal thing. i have introduced many men to anal and most of them have enjoyed it. Fingers butt plugs, silver bullets, vibrators, dildos and strap-ons. I remember one guy, that I put my smallest butt plug up there and asked him how it felt. He said he felt like he had to shit! So I knew right then he would never like anal. Being a TS Domme, whenever I put something up there, my dick gets rock hard!
