Primate researchers have found that if adolescent male primates are deprived of positive sociosexual experiences in puberty, they become inept in this respect as adults, and are unable to solicit sexual attention from the opposite sex. They hypothesized that perhaps the unusual eagerness for sex in adolescent male primates, is because its essential to their development.

It should stand to reason that humans would also have to go through a similar process to be sexually mature, as in being confident in oneself as a seducer and sexual partner. But in real life people just expect sexually unsuccessful men, who matured late socially and sexually, to wash it off and just 'be confident' when they reach college / their 20s. How do they think it works, especially when male sexuality is shrouded in shame in many human cultures, and overcoming that is by no means easy?
