The theory is you are more likely to conceive a boy if you abstain a few days before O'ing and DTD on the day you O. Other way around for a girl, DTD for the days before, abstain for a couple of days around O and let nature run its course.

I'm trying the diet thing, can't hurt. So a banana every day and I'm adding salt to my food. It's not tasty for someone who hates salt, but I figure I'll get used to it.
