if that's the case, what i mentioned in my previous post has worked a good bit for me in the past. have a friend of hers over and everybody just have some fun, maybe have a few drinks, and then somehow, you'll have to figure out what you want to do, maybe y'all see something on tv, movie, or something just casually is brought up and you have your girlfriend throw out a little tease in there and then it'll take care of itself from there. it's just a small, fun, casual way for it to be brought up and they'll end up really bringing it up themselves and you'll just be there. you won't say much of anything.
