Don't search for random because expecting guys not to hit on a girl online is like expecting snow not to melt...It's going to happen. Unfortunately for me I'm forever alone so I don't have to worry about that problem. Best thing to do is either ignore it or form a raid team of your own. Obviously your gf doesn't like being hit on, so then just ask her if she wants to stay or you'll both just go. I have a raid team of us 5 guys and 1 female, her boyfriend plays and they don't seem to have that problem.
