For the record, I'm female. And with that being said. . .
There was a time where I questioned my attraction to men (or to anyone at all, for that matter) but I eventually figured that I'd fall in love with a person, regardless of what gender they happened to be. And it just so happens that I found a relationship with a man.
I did some very light "messing around" with another girl several years ago, but it was little more than a kiss or two and some light groping. Never gone any further than that, unless you count some of my artwork.
