<human>: Can you condense the text into a few key points?

I was taking pictures with my BF's new phone. Swiped to look at the pictures that I had just taken and stumbled upon pictures of other girls butts. The girls are in clothes and don't seem to realize that they are being photographed. There were some other photos that looked like they were from the internet of beach volleyball players. Meanwhile, we barely have any photos together on his phone. I am not sure what to think. My relationship with my BF means everything to me and I am completely head over heels with this guy. I am just not sure why he has these pictures. He is not an unfaithful guy. We have great communication and from our past, we would never hurt each other. I don't mind porn but these pictures creep me out.  Guys Please explain!
<bot>: Swiped through BF phone and found pictures of random butts. Not sure how to handle or what to think of it.
