contact allergy could do it. dryer softener sheets with perfume is high on my list followed by enzymatic detergents and bath soaps. it could even be that feminine spray even if you have used it in the past. products often change ingredients without changing the brand name. a yeast infection is quite common in this area so if the itch is limited to the clitoral area use a topical antifungal perhaps mixed half/half with 1% hydrocortisone cream.
i have had a strange itch on my clitoris for a few weeks now. what may be causing this? . my vagina doesn't itch at all but it is dry and has a sour smell every now and then. the itch comes and goes throughout the day and is more annoying than anything else. i use a feminine wash and a feminine deodorant spray. i have tried to alter things by taking them away one by one and then adding them back to see if they were causing the problem but no luck. strangely enough when i went on vacation to the beach for a week the itch went away but returned once i came back home.
