I might have advice to help you, but I had recurring yeast infection and I was not enjoying sex because it was so overwhelmingly uncomfortable, itchy and irritated. This was a multi-step solution:
-always wash before and after sex, pee too
-I use a vaginal PH wash soap. Normally soaps are a no-no because the vagina is remarkable at cleaning itself, but this one helps you to feel extra clean
-probiotics- there are vaginal ones in addition to oral ones, and there are ones that are more for women too
-water - getting your daily water intake is very important.
For me, I also changed my birth control (again) to a lower dose, also seemed to do the trick. I haven't had those symptoms in over a year!
Ugh, sorry to hear. Definitely sounds like a classic yeast overgrowth. So, you've taken the oral pills from the doctor? And used OTC products? you may need another round and if you are sexually active, your partner may need to be treated as well. Try probiotic yogurt, the new drinks they make or supplements. Cut back on sugar. Wear cotton panties and try to air out occasionally (maybe sleep without undies). But a doctor should be able to swab and confirm yeast and treat. Let us know how it goes (oh, and do NOT douche). good luck
