Is it normal?

Is it normal to just not care about sex? I’m religious and did the whole “no sex before marriage” thing, and now that I’m married I can’t tell if I don’t like sex or if I just don’t like sex with my husband (as horrible as that sounds). I can go weeks without wanting sex and when we do, I just can’t get into it. I know he’s trying, but I just don’t have a lot of fun. He tries to get me off, but I just get overstimulated and it becomes annoying. If he backs off, I lose the groove and don’t ever get it back. Not sure if it’s a “we don’t know ‘how’ to have sex” problem or just a me problem. Help! TIA.
