The article has four ideas on why men like me have fewer partners. That men lack the money for partners, that the top 10% of men outcompete the bottom 90% on social media apps, that at least some of these men are homosexuals, that men prefer pornography over the actual act.
The answer for me (maybe not you) is the fourth one, "Rise of the tube sites." It is easy to fit a tube site into my schedule. It is hard to fit another human in to my schedule. After going on a tube site, I have no incentive to go to parties, go on tinder or to otherwise meet women. If I did not have tube sites, I likely would have gotten married in college when my future earnings potential became obvious.
