Could be lots of things... Hormones, boredom of doing the same thing all the time, not being attracted to him, maybe he doesn't show you enough attention outside the bedroom? There could be a lot of reasons for not wanting to have sex, but you should just do what feels right for you.
Get in the right frame of mind and try to have the sex you enjoy. If you don't want to, don't. Having sex under pressure or just to please a boy is no fun
