I am a girl, and my best friend is bisexual. I have played around with her before a couple of years ago, but I am straight and hesitant to do it again. She is all for it. Can I have some advice on if I should give the go ahead even though I know there is no way I will ever see her as more than a friend?

As I say, straight people are boring, lesbians are hot, gays aren't accepted by society, and bisexuals just want to have sex.

On a serious note, though, I frown upon sex outside of relationships. But these types of things are subjective. Your choice.
There are other factors and more possibilities may open up over time, but right now, plain and simple, it's up to you.

Well I don't think there is anything wrong with playing around. Experimentation is perfectly fine. You have to make it clear that it's just you and her having some fun and blowing off some steam together. Don't lead her on and make her think that a relationship is possible. Let her know your intentions and expectations.

That being said you sound like you're up for it. If it was a no go you would never have asked for advice. As long as you don't make her think you want to get together with her and she is all right with just fooling around then I think it's perfectly fine for you to go for it.

Thanks so much for the advice, I am going to talk to her about it like you said.
