Undies Vs. Boxers

[ShootingStar]

but does this mean day AND night? So if we want to have a girl the first time, DF should wear his undies all day AND all night? he wears undies during the day and loose cotton boxers at night..... is that the right way to get a girl???? LOL

No, the book says for the guy to wear undies for 5 days, BY DAY ONLY, during or after the period. So during the night boxers or nothing.. and not to do it any longer than 5 days. If it doesnt work for the first 2 months then stop doing the undies thing. So yeh what hes doing is right.
But you also have to do the timing thing to, which is DTD every second night up until 5 days before O. If not pregnant that month, creep it up a day each month (ie.. 4 days before O, then 3, then 2 etc).
This is what my sister did after 2 boys and got a girl, so it worked for her!
