Should I have offered?

My bf and I are both in college and went on a float trip with his fraternity. I was one of the only ones that brought a phone on the trip and got really picture happy. I took a bunch of pictures with our friend group and a bunch of just me and my boyfriend, but never offered to take some of just him and his friends without me in them. I was drunk and not thinking, but feel really bad. I don't know if guys care that much about pictures, but should I have offered to take some for him? Or would he have asked me to? I don't know if I'm over thinking this
