Here is a man discussing a new book for men by a Nick Brothermore. Nick experimented with karezza (Synergy-style) sex and finds it beneficial. The book addresses men specifically.

The author touches on various challenges, including how to present the concept to a lover.

Growing numbers of guys have jettisoned pornography and masturbation from their lives. Eventually, most of these men get into relationships with women. But if they practice orgasm-sex, their energy is sapped. On the other hand, guys who avoid sex and relationships altogether statistically have more health problems, shorter lives, and less success.

This conundrum leaves many men looking for a middle ground. Or better yet a holy grail. Sex as a fountain of energy, harmony, love, and happiness. This yearning has led to a growing interest among men in Karezza sex as the ultimate personal development super-hack. This is why this is such an explosive new book for men, a sex guide that brings a new focus to semen retention, semen retention 2.0.
