Someone I know is allergic to spermicidal condoms, but not normal latex condoms. That common? Thx (question via Twitter)
Well, allergy is one way to put it. A better way to put it would be vaginal sensitivity to bleach. Yes. Nonoxynol-9 (N-9), the active ingredient in spermicide, is a low grade bleach that we refer to as a “surfactant“. The World Health Organization frowns upon using condoms with N-9 lubricants due to their tissue compromising properties. In the spermicidal mayhem, N-9 also damages healthy tissue thus enabling transmission of all kinds of funky things. Like HIV. It’s like creating tiny entry wounds in your vadge/anus.
Just remember: Nonoxynol-9 starts with a NoNo. So only use it if STIs are not an issue and no-one feels the burn. Seriously, if it burns when you have sex, the likely culprit is the condom, lube or maybe that poison ivy patch you picked as a fuck-nest.
