What do yall think?

I'm watching the Tyra show and the subject are females who classify themselves as gay, straight, and experimenting. There are women who make out with girls and are s*xually involved with females, but the say they aren't gay or bi-s*xual; they're just experimenting. I have a friend who says the same thing. She feels that she's a straight female and is just experimenting with other females. But if you do something more than once, is it still experimenting? Doesn't that mean that they are actually arroused by females and enjoy being with them as much as they enjoy being with males- which would classify them as bi-s*xual, right? The gay women who were on the show said that it upset them when they say women who claimed to be straight making out with other women, and then claiming that they're just having fun. Or maybe these females don't want to admit that they like women because they'll be labeled as bi-s*xual and will be looked at differently by society? What do you think?
