I want to live my life, My friends are alwa...?

My friends are always gossiping about who likes who and they are always talking about their boyfriends and such. They talk about sex and private parts and all that stuff. I don't really like it when they always bring it up, I just want to talk to them and tell them what's going on! But they never let me finish without having to bring up something about relationships. It's really annoying but I don't know how to say that to them! This relationship stuff is bringing me nightmares when I sleep and I'm overwhelmed about it. I don't want too, though. Help! I really need it!
