Should i be upset?

Hey girls, so today i accidentally looked at my boyfriends phone and his best friend Adam had sent him a screenshot of a girl’s booty pic!🙄 I scrolled up and Adam was asking MY boyfriend for a dic pic to send to the girl he was talking to! My boyfriend did not send him a picture obviously but he also didn’t tell me Adam had sent him that. Also when i asked him about it he kept trying to take his phone away from me im thinking there could’ve been more pictures of other girls Adam sent him. Im very upset because my boyfriend did not tell Adam to stop sending him things like that. Im honestly unhappy with my body so i feel bad after seeing the picture. she had a nice butt lol. Anyways can you guys help me, i don’t know if im over reacting or if i shouldn’t he upset 😔
