Women are the gatekeepers to sex and men are the gatekeepers to relationships?

I used to dismiss this idea but have increasingly come to realize its merit, and I now believe it explains a lot of the problems we see today in dating and gender relations, and why so many men no longer want to get married or commit. The changes we see in women today compared to the past, the risks to men of marriage, the fact it offers fewer benefits to men now, and the fact that casual sex is so easily available, all have conspired to create a situation where men are taking their gatekeeper responsibilities much more seriously than women are theirs.
