|I want to know if blood cells mix during sex?
|Question Date: 2004-12-07|
During regular sexual intercourse between
completely healthy people, the blood cells should
not mix. However, if either partner has abrasions
or sores in their genital area, they may have an
open conduit to their blood stream. Such openings
can be microscopic, so the may not be visible or
able to be felt. Many sexual transmitted diseases
are present in the vaginal secretions and semen,
so the infections can be transferred from the
infected person, directly into the bloodstream of
their partner, via these tiny openings. Condoms
can greatly reduce the risk of blood cells or
genital fluids mixing, but abstinence is the only
way to insure this completely.
The answer to your question depends on a couple of

reproductive cells) and seminal fluid (sugar and
liquid that transport the sperm).

During sex these fluids are exchanged
and do not usually contain blood
However they can contain other
things that are also found in the blood stream.
Viruses present in the blood stream can also be
found in semen and vaginal fluid. The one you've
probably heard most about is the HIV virus which

cells do not have to be present in order for the
virus to be transmitted.
There are some
circumstances which make it likely that blood
cells can also be exchanged during sex. If one
person has a sexually transmitted infection (which
might result in an off-odor or off-color
discharge) then the increased irritation during
sex can easily lead to bleeding.
inflammation at the site of the infection also
brings more blood cells to the surface.
Another circumstance in which blood cells are
exchanged is during rough sex that leads to tears
in the skin or vaginal wall.
Using a condom
will prevent (98% of the time) any cells from
being exchanged during sex except skin cells in
the area that the condom does not cover.
Blood cells won't usually mix during sex. But you
never know if there are little wounds, and then a
few blood cells could go in or out through the
wounds or weak spots in the skin. Women will be
losing blood cells during their periods, of
course, so some of them could get into the guy if
there was a weak spot in the skin. You never know
for sure what all is going on 'down there', so you
want to be careful in case there is a problem.You
could probably learn more by investigating the
safety precautions for AIDS. That's a similar
question - is something going to go from one
person's blood to the other person's blood during
sex? You could search for something about AIDS on
www.google.com and see what you find.
Generally, no, although it is possible. There is a
lot of variation in what bodily fluids are
exchanged during sex, depending on what organism
we're talking about and what kind of sex that
organism is having. In humans, blood is usually
not one of those fluids. Sometimes during human
sex, though, skin or other tissues can be abraded
or cut unintentionally, and there might be some
small amount of bleeding. The amount of bleeding
might be too small to notice, but it may still be
there. If that happens to both of the people
involved, then, theoretically, blood (and
therefore blood cells) could mix.
