My kids were conceived in this fashion.  We wanted three kids, a boy,
then a girl then another boy.  We chose this method along with the
assumption that female sperm live longer than male sperm, yet are much
slower when it comes to racing to the egg. So depending on how many days
before or after ovulation you have sex, helps to determine the sex of
your baby.  Another way to have these assumed results is to douche with
either vinegar or baking soda before sex.  Thus producing an environment
of either acidic or alkaline.  Anyway, upon conceiving our three
children, there were in fact born in order of boy, girl, boy.  Now ages,
18, 15, 14.     I am not saying it's an exact science, but it worked for
us.
