Patient discussion about latex
Q. I went out the other day with an ex, and things got “interesting” and then he refused to wear a condom saying he is allergic to the latex now! I mean, we’ve been together a few years before and he didn’t have any problem then. So how can he be allergic to latex all of a sudden?
(we didn’t have unprotected sex if any of you wondered)
A. I doubt an allergy to latex developes over the years out of the blue, but it is not impossible that someone suffers from somewhat an allergy at a lesser extent that does not bother him and then later developes a stronger reaction to the substance. More discussions about latex
