Husband sending selfies to coworker?

Saw this on my husbands phone. Yes I went and read the messages between, I was trying to send a text from his phone to his daughter's mother and was just curious. So I saw that he was sending selfies to his female co-worker, now I just want to know if anyone else thinks that is weird or I am just being crazy. I haven't said anything to him about it either. These are all the messages I see
