Hmm, not so sure about this. Can't speak from G's experience but is it not more complex? E.g. I have never slept or even kissed a blonde lass, they just don't do it for me. Neither for that matter do Afro Caribbean girls but I'd cut a testicle of to sleep with an Indian or Pakistani girl. I don't have an attraction to men but neither do I have the knee jerk "bash the fcuking sick queer" reaction either. If it were as simple as being in your genes surely peoples sexuality would be black and white? Or should that be pink or brown?

BTW a question for you gay gents, do you feel a need to explain (I didn't say justify) to yourselves your sexual preference by this sort of means? Interested.
