My best friend is a man a few years younger than me. He’s a lovely person but he likes to chat about girls he fancies and often sends me pictures of models / actresses he likes, sometimes in their underwear or naked. He’s also told me about some of his fantasies about these girls before which frankly I don’t feel I need to hear! To me sharing this stuff with a member of the opposite sex feels like kind of a flirty thing to do and I know for sure that’s not his intention, so I think he ought to save it for his male friends. AIBU to tell him it makes me uncomfortable?
