boyfriend jerks off to porn

So my boyfriend jerks off to porn and photos of naked women or whatever else gets him on.

The thought of this makes me really uncomfortable and I just don’t think I’m entirely okay with that. The idea of him pleasuring himself to other women just really upsets me.

I don’t want to tell him to stop, as much as I’d like that, I feel like that’d be controlling and insecure of me to do. I know he wouldn’t cheat on me or anything like that and that these girls don’t mean anything to him, but for some reason it just makes me uncomfortable? It’s a feeling I can’t describe.

Do you let your partner get off on porn? Do I have the right to feel like this or am I overthinking it?
