"Oh look at me. I'm classy/cultured and upper class."
LOL
I dunno...
I first think that there are some peeps that are well not just sexually motivated, I mean it's there... but not really there, there, as in normal.
The average male I believe has some sort of sex related desire thought go through every 10 seconds...
Thing is what I find odd about your cousin is that dude likes to party, but is not interested in girls.
The main reason I partied in undergrad... and I don't think I'm the odd one here is the possibility of getting laid.
I think the whole market, just about everything around you or 80% of it revolves around the 'possibility of getting laid'.
Not Freud, just the way it is in conditional reality.
So why does he party? How does one have fun in undergrad at a party without trying to get laid? I mean that's fundamental no?
What is feminine? Is he open about his emotions and express his vulnerabilities?
Is that what you mean? Or do you mean he wears panties? I'm not sure...
If it's the former, then it would be most likely he is gay, because have a clarity in emotional expression, yet not express a fundamental lifestyle preference of male or female would not be likely as you describe him.
If he wears panties... well dude probably just is or just likes wearing panties.
Something here doesn't make sense.
Anyway...
Probably Gay.
