It's a simple cost/benefit analysis.  Women have always been prostitutes evolved solely to try and extract resources from men but back in the caveman days it wasn't that big of a deal.  The man was going to leave the house to try and kill a deer or something and if you succeeded, you would have spare food leftover and you give it to the woman.  There was most of the time no real excessive burden on the man to try and satisfy this abominable creature called woman.

Now the woman doesn't just want a piece of deer meat, but diamond rings, cars, a house that costs your entire life to pay for, weddings the price of a house, etc.  Each passing day the cost and burden of a woman on a man increases drastically while the benefits simultaneously decrease.  The prostitutes are insanely overvaluing themselves in other words.  As a man, you're entering into a contract of indentured servitude by going anywhere near one of these creatures in the modern day.  The price in terms of complete loss of freedom and all financial liberty as well is not worth it.
