Here is some sensible advice from a leading thinker and teacher: 
To be a perfect Bramhacharin (a regenerate).

1.  You must have a clean, healthy body; 2.  Good breathing capacity and some control over same; 3.  A strong will such as can move body and mind; 4.  Assiduous cultivation of the intellectual side; 5.  Control over emotions; 6.  A fearless mind; 7.  Great determination; 8. and abstemious living and high thinking.

The Yogis possess great knowledge regarding the use and abuse of the reproductive principle in both sexes.  Some hints of this esoteric knowledge have filtered out and have been used by Western writers on the subject, and much good has been accomplished in this way.  In this little book we cannot do more than touch upon the subject, and omitting all except a bare mention of theory, we will give a practical breathing exercise whereby the student will be enabled to transmute the re-productive energy into vitality for the entire system, instead of dissipating and wasting it in lustful indulgence in or out of the marriage relations.  The reproductive energy is creative energy, and may be taken up by the system and transmuted into strength and vitality, thus serving the purpose of regeneration instead of generation.  If the young men of the Western world understood these underlying principles they would be saved much misery and unhappiness in after years, and would be stronger mentally, morally and physically.

This transmutation of the reproductive energy gives more vitality to those practising it.  They will be filled with great vital force, which will radiate from them and will manifest in what has been called “personal magnetism.”  The energy thus transmuted may be turned into new channels and used to great advantage.  Nature has condensed one of its most powerful manifestations of prana into productive energy, as its purpose is to create.  The greatest amount of vital force is concentrated in the smallest area.  The re-productive organism is the most powerful storage factory in animal life, and its force can be drawn upward and used, as well as expended in the ordinary functions of reproduction, or wasted in vicious lust.  The majority of our students know something of the theories of regeneration, and we can do little more than to state the above facts, without attempting to prove them.

The Yogi exercise for transmuting re-productive energy is simple.  It is coupled with rhythmic breathing, and can be easily performed.  It may be practised at any time, but is especially recommended when one feels the instinct more strongly, at which time the re-productive energy is manifesting and may be most easily transmuted for regenerative purpose.  The exercise is as follows:—­
