FIRST: Why on god's earth would any man indicate to a woman, his woman, that another woman is 'SEXY'. Hahahahahaha!!!!!
IN GENERAL:
Men are much simpler creatures!
And, woman are much more prone to compare themselves to other women, put out those claws, be each others own worst enemies.
The thing is, to a woman, she is comparing and competing FOR that man.
She is not comparing to 'judge' men.
The objective for the woman is for the man to choose her....
To find faults with the other women.
Not to judge and find fault with the man.
(which, really, is sad.... Women should, often, be much more discerning about the men in their lives)
Men are sometimes the same way... Just usually not to the same extent...
And they self-compare themselves to other men in a much different way, and using much different things/factors to compare. ( $$$$, etc... )
Having said all of that...
Should I go out on a limb and say that, just sometimes, as a woman, I like men not for what they are, but DESPITE what they are!!!!
