Postpartum anxiety

Okay so I’ve been in such a shit place lately. I’ve been with my husband since august of 2016 married since dec 2018. And I know his past I know his partners from his past and have known it but until recently I haven’t cared but now after baby 8 weeks after baby I feel the need to ask him everything and anything about his total of 3 sexual partners two of which were one night stands. We are 5 years apart and I had never been with anyone but him. And now for some reason I feel like I need to ask all these things know all these things and now that I know them I fear I can never be connected with him sexually again bc all of his answers he gave me honestly to questions I asked is gonna pop in my head when we are intimate. And we have talked about all of it. But now idk what to do. It’s been 5 days since we last had sex I’m by nature a horny person and so is he but we can’t do anything if I don’t allow it mentally. Help me please.

How can I get these questions and thoughts out of my head. I hated who he was and in turn it makes me feel so distant from him now. Which is wrong bc he’s an amazing dad and husband. I just don’t want my marriage to fail bc of this.
