@bigfootenthusiast - sexuality has so much variation from person to person that anecdotal evidence, or lived experience, should be considered as valid as any empirical survey that supposedly offers scientific proof of sexuality's nature. The truth is, even after more than a century of psychoanalytic study and decades of genetic research, we still don't know exactly how sexuality is formed. The human brain is too complex for a simple explanation. Personally, I believe that nurture or environment has a lot to do with an individual's sexuality. So at 5'2", it makes sense that one could internalize society's messages about a short man's worth and perceive themselves as undesirable in a heterosexual coupling, leading to an exploration of same-sex desire. At 6'2", that feeling may be flipped on its head: all of a sudden you're the height that heterosexual society considers ideal, and you have more opportunities to explore feelings for the opposite sex. Desires shift and sexuality is not as stable as the "born this way"ers would have you think. I agree with @shadulti -- don't discount the possibility of having feelings toward men in the future, @Confused. Life is a buffet-- enjoy it!
