I don't know how weird or common / uncommon this is, but here goes.
Although I am not a big fan of actual anal intercourse, I enjoy and appreciate the sight of a clean, tight, well-formed female anus. When having sex with a woman in the doggy position, I always spread her buttocks apart- not just for deep vaginal penetration, but to enjoy the view of her butthole. I like to study and admire the size, the color, the roundness.
Similarly, when watching a porn, my favorite part is when the woman gets on top, cowgirl style, with the guy holding firmly onto her ass with both hands, spreading her cheeks fully apart, while vigorously thrusting his weenie into her vagina from underneath.
Does anyone else enjoy this, or am I alone here?
