The incestuous dilemma

Topic of the day: incest. yes doing it with your sibling and the immorality of it all :-@. so far so good, but i can't help but ask my aesthetics dominated self as to why? being faced with the dilemma so may times we can't even remember..., and it transcends culture and time, it's just one of those big taboos that everyone is aware of but afraid to talk about. now, why in God's name are we so eager to accept same-sex relations and contacts but heavens forbid they should be of the same family; and when it all comes down to pure aesthetics -aka looks - why should blood matter? i'm sure most of u are lifting more than just an eybrow to the topic but so what? frankly, i must say i've no brothers or sisters so i wouldn't know exactly how smth like this siblings relationship should be like, but if u consider the pure instinctual side of things and the fact that we as humans are probably the more abject and immoral and sexual of all "conscious" beings on the planet i can hardly comprehend this fear of love between brothers or sisters or both. obviously i disregard the idea of children in this case due to genetical considerations but other than that the central idea is general: pleasure - and it doesn't really matter where u get it from, or from whom or from what for that matter.
And let's picture smth else which stemed froma delightful and sparkling conv: two drop-dead gorgeous guys, twins, addicted to one another like morphine and of course the sexual tension between them. let's face it who in their right mind would turn down such an experience for the sake of ...family and relations. no no no it's just our sick twisted minds ... nothing wrong there, just like gazing at a beatiful roser in the park, cutting it savagely and getting pricked by its thorns, while with bleeding fingers u start tearing away every petal with a lust beyond urself. ok...getting overly poetic here, but still as a metaphor it works, and altough some of u are probably cursin' my ass, callin me a blasphemous bitch i still say give up on ur caged minds u sick puritanical frustrated fucks ;)))
....as a great guy once so elegantly put it: "who are u to judge something u've never experienced?"
