2. Plateau
Penis and
Testicles During the
plateau phase, the now erect penis does not undergo any new
major changes. However, the testicles swell noticeably and are
pulled close to the abdomen.
The
Bulbourethral (Cowper's) Glands The bulbourethral
(Cowper's) glands secrete a few drops of a clear liquid which
may appear at the tip of the penis. (Such a drop may contain
some stray sperm cells. This fact should be remembered by
couples who want to avoid pregnancy.)
Sex
Flush The sex flush mentioned earlier may now appear
for the first time or, if it had been visible before, grow
more obvious. Again, it should be remembered that not all men
show a sex flush, and that some show it only
occasionally.
Muscular
Tension, Pulse Rate and Blood Pressure With increasing
sexual stimulation, the entire body experiences an increase in
muscular tension, both voluntary and involuntary. At the same
time, the pulse rate and blood pressure continue to rise, and
breathing becomes faster.
Erection
of Nipples The same is true for the erection of the
nipples. However, if the nipples should become erect during
the plateau phase, they will remain so through the other
phases. |
