Is it normal my husband has photos of our friends and masturbates

I've been married for 2 months to the most amazing man. I was aware he masturbated on a regular to porn. Here is where the problem lies for me. He has been saving thousands of pics to his phone then transferring them over to his computer once his phone is to full. We have had conversations about why it is he does this. I myself would prefer he "does what he needs to" online, then deletes them. I'm having a hard time understanding the need to keep these. Prior to our wedding I had a photo shoot done and book made of some very sexy pics for him. Recently we had another discussion regarding the mass amounts of saved pics and he said he was going to delete them. Afew days ago I went into his phone to pull up some wedding pics and to my surprise not only were there hundreds of nude pics, there were now photos of 3 of my cousins. I confronted him and he came clean that he has masturbated to these pics, and their not even nude!!! He said it was poor judgement on his part. It just made is so real and to close to home for me. I understand the need or desire for men to have the fantasy world, it doesn't mean he doesn't love me or desire me. We actually have a great sex life. He is my best friend and allows me to be more free sexually then I have ever been in previous relationships.I feel so betrayed and distant from him. I'm not sure how to get past this. How am I suppose to feel at every family function from this point forward? I spent hours talking about this with him and crying over the situation. Just a little background, my previous husband of 20 years had an affair for 2 years with a woman we knew, so this really hits hard. I do t believe my husband is a cheater or would even think of straying, but the fact that he has visualized sex with my family members is a hard pill to swallow. Any feedback would be helpful...
