Am I overreacting!?

Ok please don’t judge me, I feel like I may be over reacting but I need some advice. Me & my parter are both in our 30’s so please keep that in mind. I feel like a child even typing this haha! So my husband had an Instagram account which he told me he never used/used only for fun & sports related things. One day he was showing me something & he clicked his home page & a bunch of pictures of half dressed women was all I saw.. so that was a little weird to me. But whatever, I didn’t mention it. A few months later I see him in the comments of a girls page I follow for fitness inspo.. making sexual remarks… didn’t say anything bc I know men will be men.. so then I see him a few weeks later in another girls comments I follow! (I’m big into fitness so I follow a lot of workout pages) he was wishing this girl a happy Valentine’s Day telling her how good she looked etc.. so at that point I thought it was weird & had to say something. Of course he told me things were “rough” between us and I was giving him attention so he was looking for it elsewhere.. said it was all for entertainment & I shouldn’t think anything of it. Fast forward he deletes his Instagram because of that. So then he’s scrolling through YouTube and all the videos I see are of girls shaking their ass & other things like that.. I’m trying to figure out if I’m overthinking things or is this just how men are haha! At 30 years old I’ve never dealt with this before. He also watches alot of porn & will make comments to me that I need to be more of a slut to him & act like a porn star 🧐 he tells me I’m dull and boring. I try to keep up with sex but he wants it so frequent it’s hard to keep up sometimes especially with multiple kids & everything else in life happening. When I say frequent I mean 3-4 times a day waking me up in the middle of my sleep calling me lazy etc if I don’t feel up to it at 3am.. maybe I’m over reacting idk. I’m just venting, give me your thoughts ladies 😊
