Breaking up with my baby’s dad because he wants sex everyday

And I’m tired of it. I don’t like sex and don’t want it everyday but somehow he’s a jack rabbit and shit. I would be happy to have sex once a month. But everyday ???? I don’t even get wet or aroused anymore because he’s begging everyday.. I’m tired and getting old. Idk where he has this much energy. I told him if ur threathening me for sex everyday then I’m done. I can’t do this. Why are men like this? We are both 30 with 2 toddler kids. All i wanna do is sleep and eat and repeat. Not even thinking about sex 24/7. How can men stop being so horny?
