Assuming a young man gets no interest on any dating site, he can: try the meet up site and get involved in real world activities to meet others with similar interests, or ask friends and family to arrange meetings. I know two. young couples who met through their parents, another through an on-line bridge group, another through a hiking group.
If someone, regardless of gender, is seriously prioritizing finding a romantic partner, at the same time as being in school or working, how much time is left for pornography? There are lots of ways to meet potential mates on-line or out in the real world, (through organized activities) but porn will pretty much be a waste of time if the real goal is a life mate. imho
Spending large amounts of limited free time on pornography sites or online commiserating with others in the same boat seems unproductive and counter-intuitive to me… if the individual wants a partner.
