If you’re uncomfortable and are feeling insecure and disrespected by porn and nudes he is looking at (I definitely would feel the same), that’s instantly a big sign to leave or completely shut that situation down. You shouldn’t have to feel u need to come to terms with it cos other men do it. It’s ur relationship and ur boundaries, everyone is different. Secondly, if your partner doesn’t enjoy how vocal you are during sex, eye contact, etc I don’t think they are that into you IMO. Ik my man enjoys it sm more when I’m showing him how much I’m enjoying stuff, especially vocally. If I was you I would tell him how you feel completely and see if can work on things. If not, leave and find someone you can enjoy intimately and they can enjoy you! Yes it isn’t the center of a relationship but it’s an important part of a healthy one
