Girls are attracted to primarily behaviour in men.

Guys are attracted to primarily looks in women.

If so, does this mean that the attractiveness for girls is relatively set in stone, where as attractiveness for men is more fluid and can be developed?

Or is the capacity for attractive behaviour just as set in stone? In my experience, pretty much any girl in the world could be attracted to me so long as logistics and the correct impression was made - but maybe that wouldn't be the case for some guys.

Edit: as a thought experiment, imagine a man and a women who are 5/10 attractiveness (whether that be judging by looks or behaviour predominantly) - who has the easier job of becoming more attractive?
