Dating harder nowadays
Men often define these women along evolutionary psychology lines—women who are sexually-selective, faithful, physically attractive, and have a pleasant, respectful disposition (for more on these qualities, see Buss, 2003 and my own articles here and here).Unfortunately, these qualities are again part of women's double bind, with social norms sometimes guiding them away from these biologically feminine characteristics.However, these men are often punished by being socially labeled as "jerks", "players", or even "creeps", unfit for socially-defined relationships.
Essentially, many men report that they find modern dating a primarily punishing affair.
These men may further be regarded as "just friends"—expected to pay for all of the costs of a relationship, without the physical and intimate benefits (see here).
In contrast, if men shun social pressures to be "nice" and follow what is biologically attractive, they have a higher likelihood of getting "sex partners".
Furthermore, they do so in a situation where women's own social instruction may reduce the very characteristics that many of these men desire.
Given that, many men sit on the couch, plug in a video game, and opt out—just as Behaviorism and Skinner might predict.
