Does your SO have a sort of routine when it comes to sex?

Here's why I ask. My dh has a habit of doing the same things just about every time we have sex, BUT I'm not always into it.

Like biting or spanking, for example. I'm not always in the mood for that, but he does it damn near EVERY TIME. And if I say anything to critique (like "you spanked too high and it hurt more than felt good), he acts all offended. Says I'm never happy/he isn't good enough... I just hate being bit every time we have sex dammit!!!! Some days it's hot, others it's like STOP IT!

BTW, we've been together for almost 6 years now, and we've had this issue before. He just doesn't learn.
