I think it has to do with temperature actually...or at least that is what I told my wife, as she wanted a girl.Quote from WDGann:
Genetically, it's "harder" to have a male because of X and Y chromosomes.
XX is women, XY is men. Usually, during sex, the sperm and the egg is XX but once the girl has an orgasm, the acid changes one of the chromosomes to an Y. Orgasm = Male...
I told her to grab on to my balls during intercourse and stroke them gently so that the sperm would "brew" nicely. Of course, the key is the right pressure, as you might get a scream and not a groan...
<-- nitro cooing :eek: <--- nitro screaming
I think it is men who invented romance.
