I mean… watching porn is a normal human thing to do so I personally don’t think it’s a big deal. If it really bothers you though & he knows this, that’s kind of rude. He knows it hurts your feelings so he should be mindful of that.
What about porn makes you feel uncomfortable and upset?
For me I personally don’t see it as cheating or anything bad, masturbation is a healthy and normal thing for humans to do and some people just desire to masturbate to porn.
That doesn’t mean they find you unattractive or aren’t in love with you!
But it doesn’t matter how anyone else feels about it, the most important thing is to figure out why you feel the way you do.
