Girls all claim to want a "nice sweet guy" and that "Disney fairytale" mentioned above... yet they are suckers for bad boys. What they say and do are two completely different things.
Anyway, I assume that if you're a girl who's a 7 or up, and you are smart and understand that for LTR, bad boys are a waste of time (few if any goals, bad long-term partners, probably shallow, will never be a great provider), dating is easy. You get your pick of the litter. Guys will approach you in real life, and if you go online, you'll have dozens of messages each day. Think smart and pick the ones who aren't bad boys, but have great jobs and ambition, yet still look good and are edgy or whatever else you want. Voila. You have as many dates as you want until you find a smart, well employed, ambitious, funny, cocky, fit and good looking guy. Find something you don't like over time? Dump him and get another.
The only downside I possibly see is guys hitting on you constantly, but as you get a bit older and get past the college/clubbing phase, that should be manageable.
If you're an average girl, you can still work out and be in decent shape. Seriously... if your face isn't a total disaster, a good body, good grooming and a sense of style are all it takes to attract lots of men, many of which again will be of good quality.
If you're a fat girl... I have no pity for you. Nobody wants a fattie. Junk the twinkies and hit the gym.
There is no way any girl a 6 or up should ever lack a good guy in her life. If they are, clearly they are picking the wrong men and it's their own fault.
Man, I can only imagine the luxury of guys talking to you and sending you messages daily, and having my pick of the litter. You don't even have to be passive and "wait." Since 99.9% of women never hit on guys, all you have to do is show some IOIs. I don't meant the stupid, vague, coy IOIs that girls do, but some more aggressive stuff like dropping a hints that a guy looks good, should take you out sometime, that you're single, etc. Any sane guy will do it and appreciate your candor instead of that dumb body language game.
