btw.. this is called the "rhythm method" of contraception, if it
can even be called that.
do a search in google and u can find out more. most sites will tell
u that it is having intercourse during a woman's infertile periods,
which is NOT just before or after she's ovulating... but dun forget
after ovulating the egg still has to travel down the tubes and
sperm can survive around 3 days in the vagina while
"swimming"...
