Do you think being bi-sexual is a phase?

I think sexual interest is fluid and changes as the person changes. Homosexual experimentation is fairly common in intelligent, educated people. Most of these people will eventually come to the conclusion that they like the opposite gender more and will still with that. If that is their choice, then one might say it was a phase. If, however, they decide to continue being sexual with people of both genders or only their own gender then it clearly isn't a phase.

I think there are a very few true bisexuals out there (like both genders equally). I think that most people are perfectly capable of being sexual with either gender, they simply have preferences.

Can't really speak for those that do, but most of us straight guys are appalled at the idea of being with another guy. I'd rather eat a rotten frog!

It will probably always be there, but how much it is talked about will probably depend on the overlying ideals around sexuality. I have seen a recent surge in sacred sexuality. The 60's had its sex phase, but it was not one that created connection. I am seeing a more connecting sexuality now with the influx of tantra and other sacred sexuality teachings starting to well up. As a result of that I think people (both male and female) are becoming more comfortable with their sexuality and therefore more open to the bi experience. So, is it a fad? No, I don't think so. I think it is an awakening.
