From breasts to knees and hairy armpits, if you can wedge a dick in it, someone’s got off with it (and yes, you read that right, I said armpit).    Believe it or not, there are dozens of ways people enjoy each other’s bodies, and experience explosive, orgasmic pleasure without vaginal, anal, or oral sex. Now, you’re probably thinking, “Dr. B, I’ve heard it all, and I’ve seen the porn,” but believe me, you’re about to be surprised and maybe even a little intrigued.    In the third and final installment of our series on sex, we’re going to explore all the creative and less-discussed forms of sexual stimulation people engage in, and how a pair of knees could actually be a huge turn-on!    3 Things We Learned From This Episode   What James Joyce had to say about one of the acts on my list (hint: he was a fan).   Fisting, buttcheek sex and how to tell the difference between female pleasure and the male fetishization of women’s bodies.
