So my girlfriend has this guy friend who she has been good friends with and I have grown to like him through dating her. The problem is every now and then he asks her for nudes (through text) sometimes it's obvious he's joking since they're good friends but sometimes he seems serious about it. She always tells me immediately and says no but it still bothers me that he even asks. He knows the two of us are daring since we are open about it. Anyway I could get him to stop? I don't really know him well enough to just straight up tell him to stop.
