Research shows that the stronger a man's internal drive for muscularity, the more likely he is to get divorced. This may be because the required lifestyle rigidity and self-focus—often motivated by competition with other men rather than partner attraction—are detrimental to long-term relationship health.

Men constantly grapple with a desire for high performance while simultaneously needing compassion and self-love. The internal challenge is to pursue potential without feeling insufficient, and to want support without feeling broken.

In relationships, men often try to signal safety by taming their primal edge and becoming overly docile. This "over-domestication," however, is counterproductive. It collapses sexual polarity and removes the very intensity and ferocity that is a core component of masculine attraction, ultimately harming the relationship.

A core masculine drive is to achieve and provide *for* a partner, not just for oneself. A relationship is at risk of implosion if the female partner views this ambition as selfish or rejects its rewards, as it invalidates a fundamental aspect of the male psychological need to contribute and protect.

Men often admire extremely lean physiques in other men because they represent a high-status signal of discipline and difficulty. This creates a perception gap, as women may view the same physique as less formidable or as a sign of an unhealthy obsession with looks.

Women's preference for less lean, slightly "softer" male physiques may be an evolutionary adaptation. This physique signals "formidability"—the ability to win a fight and protect—which is valued over the aesthetic of being extremely "shredded."

Research indicates women's ideal male body fat percentage is around 13-15%, which is lean but not "shredded." This contrasts with the bodybuilding ideal of sub-10% body fat, suggesting men's aesthetic goals are misaligned with female preferences.

Highly technical, male-dominated pursuits like heavy metal guitar function as an intrasexual status competition. They are not primarily for attracting women directly. Rather, men compete to establish a hierarchy among themselves, and women are then attracted to the high-status winners.

The "Dad Bod" appeals to women because it signals a man is prioritizing paternal investment (being a good father) over mating effort (attracting new partners). A hyper-focus on physique can be a turn-off, suggesting a self-centered, mating-oriented personality.

A study found that men’s real-world sexual success was highly correlated with how intimidating other men found them, not by how attractive women rated them. This suggests female mate choice is less about direct selection and more about passively choosing the victors of intra-male competition, validating a 'male competition theory' of attraction.

Despite social progress, a man's identity remains deeply tied to his economic status. When a woman in a relationship earns more than her male partner, the likelihood of divorce doubles, and his use of erectile dysfunction medication triples. This reveals a persistent and powerful link between masculinity, money, and relationship stability.
