Older man in my uni class showed me his dick pics In my class the other day this man (my classmate) in his late 40s was showing me a picture from his vacation to Spain. He then scrolled to the left and it was a dick picture. He kept holding his phone up and smiling at me. It wasn't an accident or anything. I didn't know how to react. Thinking of seeing him again next week is making me very anxious and upset. Should I tell my professor what happened?

Sorry if my English is not perfect.
