how should I feel about this?

So my boyfriend and I have been together for two years now and living together one year. Great relationship and so on ...until I started to see he was watching porn had a lotttttttt of pornographic pictures on his phone and I confronted him and said I didn't like and what could I do to satisfy you more or better..at one point I found some messages that he was sexting some girl from work and I've seen her name before and confronted him about her..he said it was work related so I let go until I found messages from her and him sexting..a lot was erased..so we had a talk about that figured things out!! Great!!...so the following day I founded bunch of naked pics and I went ballistic so said listen to me this disrespectful and if you want to watch porn we can do it together if you'd like..I mean we have sex all the time and come to find more naked porn pics on his phone ..when he told me he wouldn't do it again.. but my question is he has my pics of me naked and so on...how should I react to this? Move on or say something
