I wonder if him liking pictures of naked women or otherwise keeping in touch with various women is not just because you two aren’t a couple and he is free to do so, but also because just who he is? Just the type of guy who would like pics of naked women?

It’s neither good nor bad, it’s just how he is? Question is can you live with it if you two become a couple? Right now it’s probably irrelevant as you aren’t a couple but in the future?

It’s provably a tough question to answer. I probably wouldn’t be ok but plenty of women would be. Depends on what you can handle. It might not even be about trust but about who we are. At some point it’s just pointless to change ourselves. Too old.

Personally I’d rather a guy not looked or liked naked pics of women. It’s just how I am. I’d be upset. Well I’d likely be mad. It might not about trust but more about what you are ok with IF you two are a couple. If it’s something you wouldn’t be ok with then the person might not be right fit. Although he might not do it if you are a couple. Wonder what he thinks of it.
