Razor's right. MOST women are bi, meaning they have sex with women in between bf's. Ones who have relationship with women are pure lesbians. I have YET to find a woman who can swap around by having relationships with men and women. They're two completely seperate entities and you'd be so confused and screwed in the head if you were trying to date both. You just can't do it. Your mind can't swap from dealing with a man, and then dealing with a woman. But having just sex with one sex is quite easy to do.
