Issues or normal?

I’m 4m PP, and i am super horny. I’ve been trying to work things out with BD but he’s just kept too many things from me where i think i have an emotional sex block with him because things don’t feel as good as before. We’ve decided to co parent. Anyways, he says he doesn’t care what i do blah blah blah. I have cheated on him in the past (and confessed) but now that we’re just co parenting, would it be terrible for me To hit up that person from the past? I just want to make sure i can get with a man who knows how to please a woman and I’m not in the mood to have to re teach someone all over. I don’t recall ever being this horny before pregnancy, but i feel like an itch down there and it’s for penis. But also I’m taking antidepressants and stopped for a bit but i know when i take them, it makes me less horny so i wonder if it’s amplified because of that..?
