Edward Scissorhands – May 17, 2011

Dear Sexpert: I love it when my partner uses his hands to get me off. However, his fingernails, while clean, are yellow and thick because of “fungus.” He uses some prescription stuff and some topical stuff, which he is considerate enough to wash off before we get it on. But is it safe for him to be sticking these same fingers in my pussy? Is there any way I can catch a fungus from his nails? —Little Miss Clean Muff
