ok, this might be a dumb question, but please answer anyway! i tend to be on the dryer side vaginally (whether it's a natural thing or because of my b.c. pills, i dont know). my boyfriend and i dont use condoms (im all negative for stds, as is he) and we're monogamous. but because im often dry, i usually use my own spit as lube, giving him a bit of a blowjob before we begin the sex.
i often find myself a bit itchy a few hours after sex, though i try hard to clean up very well/urinate afterwards, its not always possible to shower after. could the itch have to do with using my spit as lube? could that irritate things down there? or is it the general dryness/friction causing the itching?
