Sex addict?

I had a talk with my boyfriend 3 days ago about sex and somehow he came to the conclusion that I’m addicted to having sex with him because I said I think about sex with him every night before I go to bed. That kind of upset me and I basically promised we wouldn’t have as much sex. I don’t want he to think I always need it. But with me being in school and my hectic family, that’s a stress reliever. What should I do???
