well... one of the tropes is 'overbearing/enmeshed mother' & absent father, hormonal stuff, cultural stuff (thailand for instance), victim of abuse..
i also believe that the only thing stopping a man from being a homosexual in practice is exercised morality because let's face it, whatever actually goes on in a straight man's mind (meaning what they fantasise about or have at least pondered) one will never know for sure
and then there are prisoner dudes.. would you call them homosexuals? how 'bout black men on the 'down low'?
how about japanese 'herbivore men'?!
and native american anthropological tribes or whatever which allow men to choose whether theyd like to be a hunter or a gatherer?
+ metro men today..
+ men who enjoy being cuckolded.. does it carry on across to that fetish? ( i am aware of the standard 'shame' diagnosis)
and the fact that gender =/= sex..
i dont really know tbh.. and i actually helped shoulder a friend who had issues about sexuality and helped him come out while i was struggling with this whole concept (mainly due to upbringing.. my mother is quite um .. vociferous about her stance of gays.. eg the anal sex thing being impure and not natural... and yet for years in the past before contraception men and women used to do it that way i think)
the thing is for me, everything not limited to homosexuality is a choice.. how we behave.. what we do.. it comes from choice..the choice to exercise whatever it is we believe and want to be. Whether or not we are aware and / want to be aware of the deliberateness of our choices is another matter.. To do so would require one to live intensely introspectively/'meta'
and to follow on from the above poster i'd like to add that that friend who i supported has had sex without a condom before.. very irresponsible but hey..
for me i acknowledge that i have little % of bisexuality or lesbianism or whatever but like.. i dunno.. i went to a girls school for 5 years and never felt compelled to do anything with anyone.. i acknowledge the that the whole gender-sex thing is complicated.. so i engage with the topic on an theoretical level..
Oh that same friend whose pain and confusion and all that I shouldered, had intense views on religion as a whole and was very culturally intolerant bordering on offensive.. (not making a statement against gays, i'm just saying that he obviously had unresolved issues cause it is possible to be gay and at peace with oneself and possessing great character but of course once again this phenomenon is rampant amongst 'straights'/ 'non gays'..). For me as long as nobody is irresponsible (meaning own up and step up in life and dont hurt others and dont use 'marginalisation'/'victimisation' as a ploy), i dont care what they call themselves and how they look (tho yes it may take me time to adjust to something i've never ever seen or encountered but i have seen a lot in my life)
