>>> why put the emphasis on sex? <<<
sex is the #1 reason women and men have relationships.
>>> sex is simply a bonus to a fantastic relationship <<<
wrong, sex is the centerpiece to a fantastic relationship. Without it, there is no relationship other than friendship. Let me give an example. My best friend is a guy...Go figure. If I was gay...And he was gay...We'd proably be in a "relationship". What keeps us from being in that relationship now? We don't want to have sex with each other. Conversely, I am in a committed...Monogomous and very satisfying relationship with a female...Whom I do have sex with. If we didn't have sex...We'd just be friends...Like me and my best friends.
You can't separate m-f relationships from sex...If you do...You are left with regular 'ol friendship...Nothing more.
