He went and watched porn in the middle of sex!

Oh my god where do I start! So first of, I’m not even in a relationship with this dude. We are just really good friends and we just started having sex. He’s always the one to initiate and I just got out of a long term relationship so I still feel a little weird about it but am still wanting it so it is all consensual don’t worry. Also he was a virgin before me so he’s not THE BEST at sex either way so I might not be getting into it as much as he’d like maybe? He can’t always stay hard the whole time for some reason and this already makes me feel ugly. Anyways he was starting to kiss me and my neck and we started taking our close off and then he stopped really fast to find his phone and was getting upset when he couldn’t. He finally found it and went to the bathroom. I didn’t know what he was doing at this point but I was already over it because I mean COME ON! So I put my clothes back on and when he came out of the bathroom he tried staring stuff again so I told him no. He then laid next to me and got on his phone where pornhub was open. He frantically got off it onto a different app. I pretended I didn’t see but now it’s all I can think about. I feel so diminished and ugly. He’s a good friend but I don’t think I’ll ever be able to look at him the same. I got a haircut last night to try and feel more myself but I need different things to make me feel confident now. UGH what do I do?
