LADIES AND GENTS!! Is it wrong for me to not want to have sex every night?

I moved in with my boyfriend about a couple of months ago, and he wants to have sex every night, and I do not. But when I don't, he says this is not normal and he doesn't want to be in a sexless relationship. He gets it, just not every night, or every time he may want. So I was wondering how others that may have been in this situation handled, or just thoughts on the matter. THANKS
