[quote name='Collectordragon']You misunderstood me. I was referring to past guys a girl has been with sexually. I don't care that a girl has dated other guys since I've dated other girls it'd be hypocritical, unrealistic, and unfair. It's what they've done with those other guys that bugs me. Some of them have been with like 20+ guys. Is it just me or is that kind of gross? One girl I went out with told me she had given oral sex to the other guy she was dating the night before. She said it very matter of fact too like we went to a movie, had dinner, and then oral. We were not in a serious relationship though she was just casually dating a few different guys including me. That still seemed nasty. Am I overacting or was that a little out there for her to do and tell me about? At least she's honest.[/QUOTE]
First off, the girl is honest, and that's extremely important. You don't want to be in a relationship with somebody who sidesteps the issue, because that's where the real risk of ending up with an STD lies. It's very important that a potential partner respects you enough to be upfront about his or her sexual history.
However, context is a factor, too. We're talking about a girl who gave oral sex to her date the night before, and then tells you about it? Not only is that gross (especially since she didn't use a condom because she "trusted the guy"), I personally would find it insulting that she'd try to make casual conversation out of her sexual encounter that happened the night before. Girls who have slept with 20+ guys? Personally, I'd pass. I'm old-fashioned in that I have little interest in casual sex and believe that sex should carry emotional meaning, but regardless I would assume (perhaps falsely, admittedly) that somebody who is this promiscuous is really, REALLY not someone you should be considering for a longterm relationship. Maybe I'm nuts, but a long list of previous partners implies to me that this person not only wouldn't be interested in anything longterm anyway, but would be more likely to use you and move on to the next guy in a short period of time.
As for the bisexual girl--dude, it's Facebook. People get "married" on Facebook because they think it's funny. It's really not a reliable source of information. You say that you've emailed her about it--If it turns out that she is bisexual, what's most important is that you are comfortable with her and with a potential relationship with her. Frankly, you already know how you feel about the situation, and if it's a major issue for you (which is fine; don't let anybody tell you otherwise), you should forget it and move on. I have no issue with you asking strangers on the internet about your love life, but make sure that you trust yourself above us.
