I’m 26, and live with an old friend. We’ve been friends since we were kids, and at first we were on the same playing field, but as we got older, he began having luck with women, while I did not. He’s an attractive, tall, white guy, so he’s pulling some pretty attractive women. Recently, he got a new girlfriend who spends all her free time here and it makes me insanely upset. It’s like this girl is rubbing it in my face that she wants someone like him and not me. Yesterday morning, I heard them having sex in his room and I absolutely cannot take it anymore. How do I express my discomfort with her presence without coming across as an asshole or total prude? He’s my friend, and I don’t want to risk the friendship over this, but he truly doesn’t understand how hard it is for me to be around her
