Porn on hubbys phone

So I was going through my husband phone and could see a lot exchanging of porn videos with his boy friends. It hurt me to see thst my husband was a part of this and was sharing videos too? Why do guys do this?

I have already confronted him about this before and he deleted them, but now I can see more on his phone? I feel disgusted and find it hard to be attracted to him. What do I do? It hurts me to see thst he also see women as sex object.
