I've been seeing more and more of this lately - guy and girl have a great first date, no sex, never hears from her again.

Many other guys are struggling to even land a date. Girls are flakier now than ever before.

Wonder how much of it has to do with the "mainstreaming" of online dating apps in recent years?

Any girl with a POF/OKC/Tinder profile has a stready stream of suitors knocking at her smartphone. Rest assured there are dozens of better looking dudes messaging her. Most of these guys won't commit but they'll hit it and quit it.

Men are as faithful as their options. Women are as choosy as their options. With dating apps, an attractive woman's options are seemingly infinite. In keeping with her hypergamous instincts, she's always on the lookout for the bigger, better deal.

In the past a woman would stick with a decent guy from her social circle after a good date because she had no other prospects lined up. Now she's more likely to stray.

Online dating is a boon for guys who fit the media-promulgated aesthetic ideal (tall, muscular, white).

All other guys who don't measure up physically have tough road to hoe. No matter how tight his "game", an average guy will always be hard-up when the Tom Brady lookalike is also messaging her .

Online dating is courtship distilled to its essence without the filter of approach anxiety.

A 1000 rejections in the real world would cripple a man. A 1000 rejections in the virtual world mean nothing.

Thousands of thirsty men without approach anxiety and hypergamous women with infinite options is a recipe for dating disaster. Unhappy girls who can't get a top tier man to commit, and unhappy men who can't get a date.

This phenomenon is unprecedented in human history.

And if online dating loses its stigma and becomes mainstream, it could put the average man's dating prospects in serious jeopardy.

Thoughts?
