am 31. 5'3 and 174. post gastric bypass pt. wore tight underwear for a couple of days and now am itching a lot. Since I changed underwear I still itch but it is better. My boyfriend also did oral sex on me before i started to itch. Also noticed my clitoral hood isn't smooth there are ridges and bumps and pieces of extra skin. Is this normal? I think I have a yeast infection. Lao been itching on my whole body as started using a different soap and lotion.
