Is it wrong for your boyfriend to watch porn?

So my boyfriend and I had a chat 2 years ago... about porn. I know some people don’t mind, but for me I feel it’s wrong and it makes me feel uncomfortable. It really hurts me to know that he’s admiring other naked girls sexually, because it makes me feel easily replaceable and not good enough, especially with how perfect they look.

Anyway, he agreed it was immoral, and he said he understood why it was upsetting to me and promised to stop. Today I found out he watches it behind my back, and he admits that he doesn’t see the problem with it.

I am really upset but am I being too dramatic about it? Is it normal for men in relationship to need porn? Because even though I’m excited a lot of the time, if he’s not feeling it I’d never dream of touching myself to another man.. so why can’t he respect me the same way or feel the same about me. Am I being over dramatic about it? Should I let it go? Or is it ‘cheating’ ish? Is it bad, like I think it is? The fact that he lied to me for 2 years is wrong. I feel betrayed but at the end of the day it’s only porn. But at the same time he knew how much it upset me and it is a big deal to me because I’m so insecure in myself.

What do I do??? How should I react????

Thank you for your help ladies xxx
