And here is a curious fact:  The hand of the opposite sex will produce effects on the genitals of the other which will not be produced in any other way.  Thus, a man may hold his penis in his own hand for a given length of time, longer or shorter, and no result will be effected, no secretion of prostate fluid be made, at all.  But let his wife take his penis in her hand for the same length of time, and the flow of prostatic fluid will at once take place.  This is true whether the penis be erect or detumescent.  If the wife will hold her husband’s limp penis in her hand for but a few minutes, even though the organ remains limp, the flow of prostatic fluid will take place!  The same is true with regard to the husband’s putting his hand on his wife’s vulva.  Should she hold her hand there, no pre-coital fluid would be secreted.  With her husband’s hand there, the flow would at once begin.

This is a remarkable physical and psychological phenomenon, and it is one especially worthy of note.  It is this fact that makes mutual masturbation far superior to auto-erotism.  A husband can thus satisfy a wife with his fingers, or a wife her husband with her hand, far better than either could bring himself or herself to the climax alone.  This point is of great import, in considering many of the sex acts of husband and wife.

As a rule, let the husband and wife do whatever their desire prompts or suggests, and just as they feel they would LIKE to.  Only this, let all be in moderation. Carry nothing to excess!

Which suggests the question often asked:  How frequently may coitus be engaged in?  The answer is, just as often as is desired by both parties, but never to the point of weariness or depletion of the physical, mental or spiritual body.  Use good sense here as elsewhere.  We eat when we are hungry, but it is wrong to gorge oneself with food.  The same rule holds with regard to sex exercise. Satisfy the calls of nature, but NEVER, overdo the matter.  BE TEMPERATE, MANLY, WOMANLY! Don’t be afraid or ashamed to do what your desire and your best judgment say is right.  Use common sense, and you will not go wrong.

And don’t wear each other out, either both together, or the one the other.  Many men insist on their rights (THEY HAVE NO RIGHTS) and greatly debilitate themselves by excess of coition with their wives.  Per contra, there are some women who wear the lives out of their husbands by the excessive calls they make upon them for sex-gratification.  In the latter case, a man will “go to pieces” much faster than a woman who is over-taxed.  To satisfy such a woman, a man must spend at least once every time his wife calls on him.  This draws on his vital fluids, at every embrace; but, as has been stated, there is no escape of vital fluid from the woman, when she spends, and so she can reach and pass the orgasm, time and again, and still not have her vitality taxed.  Indeed, in some cases, the oftener a woman spends, the more animated, robust and healthful she becomes.  In case unmatched people meet as husband and wife, they should do their best to adjust themselves to each other’s condition, keeping always in mind the best welfare, each of the other.
