I enjoy anal play, and I am a guy. Sometimes getting rid of the hair makes things infinitely more fun. I've gotten pretty good at shaving my own ass and crack, but there is something incredibly enthralling about taking turns shaving each others genitals/ass... it's amazing how it always ends up being sexual.
So, I will shave a gal and have been the shavee before.
Don't knock it till you try it.
