Venting sex drive

Just venting here. Long term relationship, we now have a 1.5 year old. In my relationship our needs are not being met, it’s very hard at home. That being said my sex drive is pretty much not there at all. I don’t want it. I don’t care for it. My SO has a high sex drive and he hopes to be sexually active well into his old man years. I worry about our future a lot. I can’t give him what satisfies him. We have other issues as well but the sex thing is a big one. How do I get my sex drive back?

Also to add to that, I’ve never had much of a sex drive. I was r*Ped as a kid and always had a really negative experience with it, I really don’t like being touched. But before kids I was more confident than I am now so I passed for being flirtier and better able to please my SO. Now that’s completely depleted & I know it really puts my SO down. He wants to have fun and live a simple life with happiness & sex and I feel like I really can’t contribute to either. Help.
