Personally, I think sex should be like math. At school. No one cares if they're crap at math. They even proclaim it. They'll say to anyone, "Yeah, I don't mind science and English, but I'm absolutely shithouse at math." And other people would laugh and say, "Yeah, me, too. I wouldn't have a clue about all that logarithm shit." You should be able to say that about sex, too. You should be able to proudly say, "Yeah, I wouldn't have a clue about all that orgasm shit, ay. I'm okay at everything else, but when it comes to that part I wouldn't have a clue." No one says that, though. You can't. Especially men.
