Open Question: How do I react to this? Is what he did wrong?

[feedcrawler]

Well, to start off, I have been with my boyfriend for a year now and we are in a loving, committed relationship. Since he doesn't have a very strong sex drive, I never worried about him having a wandering eye. Well I'm gonna cut to the chase. He has a foot fetish. He loves my feet, and always gets off to them. Yesterday we were at the park and laying down on a blanket in the grass under a tree. I was using his phone to take pictures and I wanted to see how they came out. I opened up his pictures and I looked through the pictures I took and went a little far back and found pictures of a girl sitting at a computer. All the pictures were focused at her feet underneath the table. I asked what it was, and he said he couldn't tell me because I'd get angry. He works at a library at school, and I'm guessing he saw the girl and took a picture of her feet because he found them attractive or something. I asked him again and he told me "I'm sorry. I was being stupid. I was being a stupid little horny guy." I was really hurt. He said he was planning to use the pictures later to get off. He took this picture during a week that he was ignoring me because he just wanted time to himself. I don't know what to think. I want to trust him but I feel disgusted by what he did. He went out of his way during work to take a picture of another girl's feet. I never thought he would do something like that. How should I react to this?
