of
coitus possible! Among mere animals, the male is always upon the back
of the female. They--mere animals--can never look each other in the
eye and kiss each other during the act! This is another marked and
very significant difference between human beings and all other animals
in this regard) it is perfectly natural and easy for the organs to
go together, when properly made ready, as here-before described. The
woman should also place her heels in the knee-hollows of her lover's
legs, and clasp his body with her arms.

The entrance of the penis into the vagina should not be too abrupt,
unless circumstances are perfectly favorable for such meeting and it
is _the wish of the wife_ that it be made in this way. It is only
fair to say, though, that such bold and pronounced entrance is often
_greatly desired by the woman_, if her passion has been fully aroused
at this stage of the act. Such union is not infrequently of the
greatest delight to her, if everything is favorable for its being
so made. But, if there is any pain produced in her by the coming
together, the meeting should be gentle and slow, the penis working its
way into the vagina by degrees, till, finally, it is entirely encased
therein. Once thus happily together, the vagina and uterine cavity
will still further expand, till, in due order, the two organs will be
fitted together perfectly, a single unit, _one_, in the highest sense
of unity.

This is the _second_ act in this wonderful play.

Once well together, and the organs perfectly settled and adapted
to each other, the _third_ act begins, namely, _the motion of the
organs_--the sliding of the penis back and forth, partly in and out of
the vagina, though this is not really the best way of describing just
what should take place. What _should_ actually be done is, that the
_two_ organs should engage in this motion, which is _common to them
both_. They should _mutually_ slip a few inches, back and forth, _each
party to the motion doing a fair half_.

It is often supposed, by both an uninitiated husband and an "innocent"
wife, that all the motion should originate with the husband--that
he should slide his penis in and out of the vagina, while the woman
should lie still and "_let him do it all_." This is, however, a
_great_ mistake, and one that has caused an endless amount of ill to
untold numbers of husbands and wives. And for the following reasons:

In the position just described, if the wife has her arms a
