I had a life changing experience at age 22. A manic crazy group of Peruvian girls brought me home from a nightclub to their party. Okay, we had a nice night, but in the morning - seeing the girls without their hair, makeup, looking hungover - it's like, wow, highly sexualized doesn't mean beautiful. It just means highly sexualized, which comes from a lot of work on her part. But as you saw in the Okcupid article, highly sexualized draws men's attention - "flirty face", the Myspace pose, etc.
But getting one of those flirty, sexualized girls doesn't mean higher quality! It just means you got a girl who put work into appearing highly sexualized, which if anything, is the sign of maybe a fun fling but not a quality girlfriend.
Me, I stopped looking for that, and started looking more for just decent quality skin, a walk with some energy in it, awareness in her eyes, and so on. You can always teach a girl how to dress and make herself up to your tastes, which I did for my last serious girlfriend who was getting her PhD in physics. Too much jeans and sneakers when I met her, lots of skirts and dresses and leather boots and heels when I moved out of the USA.
But I like a lot of other things that most men don't - I prefer taller women, and I prefer women who are built strong with good musculature, athletes, and girls with wider hips and shoulders. It always amazes me when I meet a girl who is an athlete and she's getting so much less attention from men than a girl who is on the alcohol + cigarettes + no food diet.
But I digress, quality is quality, and if you can find quality with less competition, that's absolutely worth going and getting. Going for a girl who is equal or lower quality but more highly chased doesn't make your life better, it's headache for (at best) ego-gratification, at worst a waste of time.
