Did you successfully figure out the cause? I myself have dealt with this same thing twice before, it lasts a few days then clears up on its own. I'm now currently dealing with it again and am not positive to the reasoning. I have a very stressful job and suffer from insomnia and wonder if those things make a difference?
Thanka for the help, it seems to be clearing up but I've booked for the gyny just to be sure
best to go to a gynecologist to be sure.
It could be a number of things- irritation in the vagina is common, as it require a level ph to feel normal- soaps, stress, hormones can greatly effect this balance.
You probably are just having a reaction, or thrush or something- try not to touch, maybe use cortisone cream if it in unbearable, but book an appointment with a doctor asap just to be sure as some std can be caught without sex (rare but possible!)
