Ok this has been happening for a looooooong time pretty much since I started having sex consistanly which is only about 3 years... at first, after having sex I would notice during the next few days my vagina would be dry and have a different smell...it wouldn't stink really it was just not my regular scent... i thought it was a yeast infection so i used a 3 day otc treatment and it cleared up... but it kept happening....then i had to use 2 because the first one didnt work... it started to really affect my sex life. I didnt have sex for about 10 months and during that time i was perfect down there!!! I didnt have problems wit dryness during sex just after I wouldnt even have sex while this was goin on... I thought it might be an allergy to latex but nooooo... because it doesnt itch...its just dry and smell kinda like... dirt or dust...weird huh? The oct yeast treaments clear it up with one or two treatments but i know its not a not a y.i. so what is it help
