When Your Penis Is Partially Erect
Or Loses Erection Quickly
penis is made up of three chambers of spongy tissue; two chambers
on top (the corpora cavernosa) which extends well into the body
to anchor the penis, and one underneath (the corpus spongiousm)
which becomes the glans or head of the penis. The
three tubes are surrounded by a sheath of skin which stretches
but to a limit. The arteries which feed blood to the spongy
tubes are surrounded by smooth muscles fibers which are normally
contracted, limiting the amount of blood entering the penis.
When a sight,
touch, or thought cause sexual stimulation, the brain signals
the muscles to relax, greatly increasing the blood flow. That
is why stress will sometimes cause a man difficulty getting
an erection because he is unable to relax. The spongy bodies
fill up, making the penis enlarge and become erect.
