When at bars or parties my girlfriend kisses her room mates (all girls). I'm not really concerned with most except for one of the friends. Recently her friend confessed to saying she was in the top 5 for prettiest girls at our school and that she is attracted to my girlfriend. My girlfriend said she is attracted to her friend to and that she finds the woman figure attractive as well. She claims she could never get sexual with her, however I'm still concerned with the intentions of her friend maybe trying to work her way in between her and I. She knows that I get a little uncomfortable when I see her kiss this particular friend because her friend can get way to sexual with where her hands go. Should I be concerned about this? Her friend had a little fling with a girl for about 2 months btw.
