So much she can’t afford it

It just hit me, but I think Rush Limbaugh has no idea how birth control works. He seems to think you take a pill or get a shot for every sexual encounter, judging by his statement “[Fluke]‘s having so much sex she can’t afford her own birth control pills.”

Does he think the birth control pill is like Viagra? I know he judges most things through the lens of Oxycontin, but you don’t grind up and snort a handful of progesterone pills whenever you have sex, you just take one daily.
