Awkward... A massage can be just a massage though. It all depends on the girl and who the other guy is. I have no problem giving a back massage to someone I know and who is in real pain or discomfort. If I have a feeling that it wouldn't matter to them who gave them a massage because there aren't any ulterior motives, than it would be ok. I have no problem doing it in front of my bf either. If I had a feeling the guy was trying to flirt though, there's no way he would be getting a massage from me. I would actually be really irritated with that guy, since it would mean he doesn't respect the fact that I'm in a relationship. Therefore he doesn't respect my choice, which means me.
