There is a lot of literature out there on the subject. The Cherry Cola Hole, or anus, as some of us know it, is very sensitivie. Simply licking or touching it can stimulate a woman. Inserting blunt objects like bats and footballs is a no-no, but fingers and your little guy can further stimulate regions inside. It's on the other side of the vaginal wall, and I have read about how women can get monster orgams through anal sex. I have a good friend who loves it, and she just teases me with the prospect of seducing her. Damn cocktease.
There was the question about whether us guys would want a woman going near our butts. I am probably in the minority, but I believe in exploring each other's bodies. It raises the amount of trust and security you feel with each other. Now, I don't want her applying a strap-on and slamming my ass into a bloody mess (aka Herr Starr), but I have heard about how massaging the prostate can induce intense orgasms. That means wilder/more enjoyable sex. So, if I find a woman without long fingernails who talks dirty and is good with her hands... well, I am game.
