A book about the demystifying factors surrounding men's sexual health and its parallel effect on men's mental health: Why men fake It by Dr. Morgentaller.
I reccomend it for anyone who needs a reexamination about what is inappropriate or appropriate to think about men's bodies and the what's and why's do we do things.
One such reexamination was how women in a relationship with one of his patients treated him when they found out he couldn't orgasm or ejaculate not because the patient had no sexual interest in his partners but rather that his body wasn't allowing such a reaction under normal circumstances and instead needed sensory stuffs to get off.
