What kind of pervert, anti-human-nature "culture" and "philosophy" you are talking about? Haven't they victimized and taken the happiness away from enough people already? Not to mention that being a Brazilian I suppose you should appreciate the positive value of sex very well?

How does it draining energy mean it won't help?

And by the way: http://www.cnn.com/2012/08/10/health/sex-athletes/

It's "common sense" in many cultures that the opposite is true.

More importantly, the positive benefits of regular sex have been made evident by virtually every study ever done on the matter.

Another datapoint of common-sense being bullshit.
