Labels are not important. I think we are all potentially bisexual in that if we weren't worried about labels it would be possible to enjoy oral sex (getting or giving) with another male. I haven't actually tested (or tasted!)that theory, but am "man enough" to acknowledge that the idea of it is very interesting to me and arousing too, as is looking at all of the fine examples of manhood on display on this site, regardless of what % straight/gay the owner says he is.
