Ok. so I had posted on here earlier that my vagina has been itching but only happens after sex. ( We use condoms ) I was wondering if you can randomly become allergic to condoms? I have never had this problem before but this last two times we have had intercourse I get really itchy down & I mean REALLY itchy. It has calmed down but now it's irrated as I was scratching down there, I know it shouldn't have but it just felt awful.
