1) They are usually more mature
Yeah, mine sure is.
1a) this includes sexual maturity
How exactly are you defining that? Physical development, sexual experience, sexual outlook?
2) They are usually smarter
Regional bias here: going from rural Deep South women (and, truthfully, people in general) to my current girlfriend was... oh my god. I felt complete because I could actually fucking talk to her about something intelligent. And yeah, I know, that's unfair as hell, there are smart Southerners of both sexes, yada yada well that's nice and all but fact is the majority of 'em down here just plain ain't.
3) They are usually more stylish
Reference: I attend LSU, and my girlfriend goes to SCAD, but takes classes at LSU right now. She may literally be the only (non-faculty) woman I see all day who's not wearing a tank top, Nike shorts and running shoes. Could be my location, could be my poor life choices, but yeah, my girlfriend is much more stylish.
4) They are exotic, but still white for people with ethnocentric sexual tastes (most everyone unfortunately)
Guilty. And I really wish I weren't, but yeah.
4a) They usually speak like 3 languages, which is hot by itself, and also exotic
Truth. And true here. (And the best part is, I'm picking up a little bit of it. So if I ever have the urge to say something sweet to her around other people - don't judge me - I can just drop a few words I picked up in Russian and bam! Done.)
5) They have accents that are romanticized by our media - British, German, French, Spanish, Russian, doesn't matter, hitting on (or being hit on by) a girl with an accent like that is automatically more sexual because of our cultural view of these accents in the opposite sex
Hadn't even considered this, but yeah.
6) You automatically have more to talk about - they are interesting just by virtue of being non-American.
lol. Also true. Of course, you gotta step up your game, too. Go out and see some fun shit, do some fun things, something to match "So back in Europe, I..."
7) There is smaller chance that they are physically... erm.. unfit. To be polite about it.
lol. Addendum, the Europeans I do know have MUCH healthier diets. Which has benefited me a lot, because she usually picks the food.
8) And finally, and most shallowly of all - getting with one is a more impressive achievement that an American, therefore your bragging rights are increased.
Yep. Although, admittedly, I don't ever take satisfaction out of this unless someone explicitly brings it up. If no one attaches value to it, idgaf, but once someone starts gawking about European women and someone happens to mention her...
