I'm not a big fan of pigeon-holing people - I prefer to think of us all as being on a spectrum, somewhere between liking only men and liking only women, with liking both equally in the middle.
The number of women I've been attracted to is very small, but it is non-zero, so I'm not 100% gay, but I'm definitely closer to the gay side of the spectrum than the middle, so I voted gay.
