Nope, I don't think you're alone, or outlandish.

Sexuality is a spectrum, and prone to gradual, subtle changes throughout our lives, I'm pretty sure.
I have never been in a relationship. 26 years old and never even kissed another. At this point I'm not sure that will ever change. The prospect of a relationship scares me--I fear getting too close to anyone else--and sex isn't of much interest, though I'm attracted vaguely to men. I'm not sure where I stand as far as gender even goes, so I think that muddies the waters considerably.
