As a person with a nut allergy, I’m used to reading ingredient labels. But I recently learned that there may be also be traces of nuts in…nuts!

Last year, a woman in Surrey became the first known person to experience sexually transmitted allergies, triggered by traces of Brazil nut in her partner’s semen.  This adds a whole new dimension to the concept of safer sex!

p.s. Check out Story of Alice!  Not only did her blog lead me to the preceding discovery, it’s full of explicit goodies like erotic literature, tips on oral sex and lots of pretty pictures of pretty people doing sexy things!

    Now could the same happen in reverse? Could a woman who eats something that would trigger an allergic reaction be absorbed through the mouth or penis? Makes a guy with allergies wonder…

      I’ve been wondering the same things. Trace elements of our diets do wend their way into our bodily fluids including semen and vaginal lubrication, although usually not in quantities that would trigger an allergic reaction.

    Crap. How the heck are we going to label those?

    Damn it. I’m allergic to all nuts except peanuts and am deathly allergic to Brazil nuts. :(

    • nadinethornhill says:

      So am I. Although I’m guessing in this case the guy either ate a LOT of nuts or his partner was unusually sensitive. Otherwise, this would probably happen far more frequently.

    Damn… not something I’d have thought of…

    Wow, that is quite alarming. As if I needed something ELSE to bring up during The Talk with my kids. SHEESH.

      Tell me about it! I plan to include in my list of ‘Why condoms are a good idea.’
