How do you make a boy when getting a woman pregnant?

Have the woman standing on her head for 10 mintues during and after your ejaculate. Then, carefully help her down from this position in order to ensure that your ejaculate doesn't spill from her and allow her lay on her back from 1 hour while you sing Barry White's "I've Got So Much To Give" to her vagina and stoking her stomach region with a luke warm wash cloth.
