Being self-confident and "yourself" (<---Alpha) does not necessarily mean you're going to get laid frequently.
For instance, next week I'm heading up into the mountains for a few days to go fishing, rock climbing, then coming back down to the beach for a few days of surfing.
That to me sounds like a good time.
Meanwhile, one of my friends is heading out to the bars/clubs 7 nights in a row.
We are both about equal in appearance (6 or 7/10) and game.
Guess who is going to get laid?
He has far more chance of getting laid next week than I do, despite my lifestyle being arguably more "attractive" and "alpha" to women.
Doesn't matter how Alpha you are if you don't put yourself in a position to meet the kind of women you're interested in.
I spent my final year of highschool driving out into industrial parks to play paintball, hitting the gym, surfing every weekend, and pool hopping after getting drunk.
Sounds like fun and interesting and attractive to women right?
Maybe...?
We didn't give a fvck about getting laid, just having a good time and doing interesting stuff. Thats what all the PUA material says to do. Don't give a crap about it, just live an interesting life, have a good time and women will be drawn to you like a fvcking magnet.
And guess what...?
We rarely got laid compared to some groups of "interesting" guys who just spent all week(end) going to bars and clubs, standing around in circles jibbering like monkeys to eachother about facebook, movies and titties.
Being truly Aloof and "Alpha" will not get you laid.
You still have to make an effort to meet women, whether its cold approaches, or situational/context approaches.

edit:
the only plus in regards to getting laid due to being an interesting person with a fun lifestyle, is that you become a 'thief'. Guys cant leave their girlfriends near you, because after hanging out for a short time the girl realizes how boring and beta her boyfriend really is. Next thing you know we're texting each other and arranging to "fool around" in the back of my car or at her place while her housemates/parents are away.

I guess in short, by really being a fun person who does exciting and adventurous/dangerous things, you end up with an Ace card up your sleeve. But you don't win the hand if you never play it, and by doing fun stuff you never have time to play it.
You'll have your pick of great women, but only when/if you make time to meet them, which in my life is rare.
I guess quality > quantity, but IMO a guy in his late teens--twenties, needs quantity as well.
So don't be too interesting, or do too much fun/exciting stuff, or live too adventurous a lifestyle, or else you'll never meet any women.
