Squeeze an aspiring between your knees

No surprise there. Women compelled to wear burkas will probably relate to sex and sexuality differently than more sartorially liberated western counterparts. Women who've grown up getting told by creepy old men to squeeze an aspirin between their knees are liable to self-report more conservative behaviors and attitudes about sex.

Huh...??

I think Marshalette is referring to this: Santorum Sugar Daddy Foster Friess Gives 'Gals' Contraception Advice: Put An Aspirin Between Your Knees | ThinkProgress

Read the article. Still doesn't make any sense.

Well no but did you expect it to make sense coming from those people. I can explain the aspirin between the legs thing. Theory is that if you hold an aspirin between your legs then you can spread your legs so you can't have vaginal penetration and therefor can't get pregnant.
Obviously these people don't know much about non-traditional sexual positions
