If men don't acts as partners to their wives, being an equal partner with the domestic labor, women start seeing them as one more child to take care of. And who wants to have sex with their child? Gross.

In addition, men who make no effort to please their wives in bed (SOOO many women aren't having orgasms during sex), are never going to be wanted sexually. When sex is simply a selfish game for the husband's pleasure only, of course his wife won't want it.

It's really not rocket science. She didn't emasculate him. He emasculated himself by forcing her to be his mommy - cleaning up after him, carrying the full mental load of caring for a family, and generally not being able to rely on him emotionally as a partner.
