why don’t we have sex?

My husband and I have been married for a little over three months. We didn’t have sex before we got married. But he did masturbate quite often from what I’ve gathered. (Which is fine) he always said things that lead me to believe we’d have a pretty consistent sex life once married. We haven’t had sex in weeks. When we do, I always feel like I’m the one that starts it. He doesn’t really show an interest. Long story short, I know he used to have a pretty high sex drive, he made comments about us having a pretty good sex life. Now that we have slept together it’s almost nonexistent. So does he not enjoy me or what?
