Sex drive or something else?

So I’ve only ever slept with one man, my husband. Met him when I was 17 and we have been together since (now 34). We have a baby together and since then (and a bit before that if I’m honest) I’m not too into sex.. I’ve never experienced anything else but don’t seem excited by it anymore.. I did initially, when we were young.. I’ve had silly crushes on other guys but am pretty shy/awkward too..

My husband has cheated on me a couple of times in the past as we were growing up which was so hurtful at the time but we have moved past it..

Not sure I’m too fussed about sex at all tbh..

Any advice? I don’t feel overly confident with my body either right now so that doesn’t help..

Thanks in advance.
