Is he cheating or am i over paranoid?

This is gonna be a pretty long post so please bear with me. Before i explain my problem, i want it to be known that my ex and father of my child cheated on me with quite a few unattractive females and his sister as well (disgusting i know). So i might be paranoid and over thinking things.

So i need honest advice if it's just me being over paranoid or my current BF doing me wrong...

My bf and i have been together since 8/19/16, so it's almost going to hit a year....when i first met him i had zero interest in dating due to every guy i was with was nothing more but a disgusting pig or a filthy cheater.

I'm the type of gal that thinks porn and strip clubs are considered cheating.

I made this VERY clear in the dating process and he said it was ok with him. That he didn't do that type of stuff in relationships and he claimed to hate men that are sex driven.

Well the past 2 months he's barley been wanting to have sex but wants blowjobs constantly. He's also been selecting movies or tv shows with nudity in it. He's also been deleting his phone history (Which he's never done before ) and sometimes when i look over at him when he's on his phone, he tilts it a little like he's hiding something.

And the rare times i get him to have sex with me he never wants to be on top and he closes his eyes every here and there.

I've gotten so paranoid that i looked back 2 years into his FB and he shared lots of disgusting posts with half naked women...yet he swore he hated men like that. And the most recent one was 6 months prior to us dating.

He also never wants to do anything anymore except play video games or talk to his friends.

But when he is paying attention to me, he's very sweet. Gives me massages, cooks for me, does what i want to do, give me lots of affection...and he's great with my daughter.

I just moved in with him 5 days ago but all 5 days we've been fighting and twice he slept on the couch.

Could i be overthinking stuff and confusing his stress with cheating? Or is he doing something.

I strongly feel like he's been jacking off to porn and thinking of other woman, but i am biased due to past relationships.

Please help! Thank you for reading.
