Well this is little bit tricky but interesting question. I would like to say that men it comes for ejaculation then men should be careful of it. men should already practice a controlled frequency if they want to increase longevity, health and strength.
And it completely means that men should engage in sexual intercourse along with other activities but should be in limit they ejaculate as part of session.
One thing you should know that “ man might achieve health and longevity if he practices ejaculation frequency two times a month, means 24 times a year. Apart from it, if proper attention for diet and exercise is taken he will also have a healthy life too.”
However, I would like to say that how often men should ejaculate is completely depend on man as a part of sexual activity. In this, men should know their own frequency by analyzing how refreshed and determine they are feeling after their intercourse session.
