Testicular self-exams (TSE for short) can be a good way for men tolearn what their testicles (also called testes) normally feel like so that if there is a new lump or other change, they will notice it and can seek medical care right away.
Fyi, a narcissist may learnto approximate such behaviors as they seem like a good idea to him, and may also love his children because he sees them as an extension of himself.
