Hi, I agree it is most likely a yeast infection. Don't know about the skin flap. I have always treated the yeast infection with an OTC 2-3 day yeast treatment from a drug store. It always works for me. If that doesn't work go to see your GP and you can then ask about the skin flap. A lot of the time the yeast infection can make you feel like you have a urinary tract infection. If after the yeast treatment and if the yeast symptoms go away and you still have the urinary symtoms go to your doctor. Just my opinion from experience.

sounds like a yeast infection and possible hemorrhoids.....you should really go see your doctor about this.
Vaginal itching and discharge sounds like you have a yeast infection!
I suggest seeing your doctor for an antibiotic! As for the flap, Right under your vaginal opening is a flat length of skin called the perineum (pair-ee-nay-uhm). Below the perineum is your anus.
