My reading of brain research has pointed toward the conclusion that human sexual orientation is more fluid than is culturally believed to be true. This has been heretical to say. If you are from a conservative religious perspective as I am, it was considered homophobic to say lest it undermine the gay political arguments. But also, it is usually not the way we experience our own sexuality as the following author also admits. The linked article is by a gay author who is arguing for the fluidity of sexual orientation, not just from his personal experience, but from scientific evidence and the conclusions of respected groups as well. He holds that sexual orientation derives from multiple sources.
