[16] The instructor of young men should not allow confusion to arise
from the recent contention of some medical men that emissions are
abnormal or unnatural because they are not known to occur in animals.
Certain it is that they are adaptations to changes caused by enforced
sexual restraint after the seminal secretions begin with puberty. Such
restraint is, of course, abnormal or unnatural if we compare with
animals; but many of our acts are unnatural and not necessarily
unhealthful. For instance, the sedentary life of the student or
professional worker is abnormal or unnatural, but it need not be
unhealthful, if hygienic adaptations are made. Likewise, seminal
emissions are unnatural for primitive men or animals without sexual
restraint, but this does not mean that they are unhealthful for
self-controlled men. Here, as in many other cases, comparison with
animals is misleading and does not teach us useful facts concerning
human sexual functioning. The truth is that physicians have no
evidence of harm from emissions that are not caused by voluntary
activity.
