This is such a tough one, girl. If she were sleeping around, I'd say that you'd have to say something, for health reasons if nothing else. But since it's just making out, is it really physically endangering anyone? I guess I would talk to your friend again. Tell her that her behavior really bugs you and that you feel bad for her man. Encourage her to work through these lack-of-romance issues with her man instead of sucking face with random people.
