I was reading this today from a book I found here in the library and it kinda freaked me
out...
"The practice of anal sex may lead in itself to a dysregulation of the immune function
of the human body through sperm (foreign protein) deposited into the rectum. This
dysfunction does not occur in heterosexual sex, as we have already mentioned. The thick,
multi-layered walls of the vagina protect the blood from the direct penetration of sperm
into the circulation. However, if sperm penetrates the thin and damaged walls of the rectum
it is recognized in the blood as foreign protein which challenges and thus stresses
the immune system. This results in an immune dysfunction, even without the classical HIV
mediated immune suppression.
For this reason alone even monogamous anal sex is not a safe alternative to vaginal
sex since about 75% of passive partners in monogamous couples showed sperm induced immune
dysfunction. Their immune systems showed abnormal function even though they were not
infected by HIV.
Therefore it is physiologically abnormal to deposit sperm in the rectum since it
overstresses the immune system of the recipiant if it reaches the blood stream. The
immune system cannot cope with the massive quantities of antigens of the sperm. The body
then becomes endangered by infections since the sperm penetrating the rectum weakens the
defence afforded by the immune system."
I don't want to stop having anal with you, I just think if we do do it, that we should
use a condom.
