Internationality

Men are dangerous mammals in general. Throw in above average good looks, charisma and some game and you've got a lean, mean wooing machine.
Allow me to use three nationalities as examples.
Greeks, mestizo Spaniards and Indians seem to have something in common - their beautiful deep set eyes and their charm. (Before you rise up in arms, I will state that Filipino men have these attributes regardless of whatever. It is a given and including them would make all this sound redundant.)
Yes, their women are attractive, but right now, it's the men I want to focus on.
So far, and from what I've seen anyway, the men of these countries have a strong sense of self, are quick to bring out the charm in whatever form they deem useful at the time, and know, just innately know that they are irresistable.
And its not just the looks mind you, it's their take no prisoners approach to wooing the womenfolk - whether by sugar laden outright flattery, shock treatment bordering on obnoxiousness or a raw display of their many, many "talents" - these guys will make sure they get the intended results. That is of course, undivided attention bordering on adoration and possibly, if things went well, a hook up for the evening.
Women within a ten foot radius are reduced to simpering, jelly like beings.
Author excluded - which is not to say that I do not appreciate the occasional charming sentence thrown my way - hey, only human!
One should be careful when handling men of this nature...blessed with good looks, innate charm and charisma, they make for wonderful adversaries who should be treated as one would a mousetrap - inspect it, have a bit of a sniff of the bait, and then walk around it and away.
