afterhours, that's a very good question. empirically it's the case: i really would NEVER cheat a friend, a business partner, not even a stranger on the street. however, sexually, i cheat all the time. strange huh? but true. by empirical observation, that's just the case, that's me. some moral majority fanatics around here would like to deny it but it's absolutely true--i'm a completely honest, trustworthy, responsible guy, right up until it comes to fucking.
it's the reason why once upon a time i posed that thread: would you fuck your best friends wife? most of us here on terb cheat on our OWN wives all the time. by your logic that should be worse than cheating on a friend, right? i mean, wife is closer than friend. in the circle of "closeness" it has to be worse to cheat on your own wife than to cheat on your friend with his wife.
however we all know, viscerally, that this is not true--it's worse to cheat with your friends wife than to cheat on your own wife.
so the logic you're outlining, this notion that it's worse to cheat on the people you're closest too--well it plainly doesn't work logically. it just doesn't. sexuality defies that kind of analysis. at the end of the day it's just not as logical as everyone here would like it to be. at the end of the day fucking behind your own wife's back is not as bad as fucking your friend's wife behind his back. explain that one, without reference to the complexity of human sexuality...
my conclusion--sex is just different. we apply different rules to it. the "moral majority", sw1tch et al, can deny it--but everyone here knows it to be true.
p.s. -- i'm appealing to humanity rather than logic in this post because i'm drunk, it's 3am, i just got home, was out with a good friend of mine and had a great night. ask me for a more logically succinct answer tomorrow, if you don't like this booze laden one.
