My boyfriend and I went to Pizza Hut and after eating we got me he fingered me without washing his hands an performed oral on me. Then I took a shower two hours after. The next day when I woke up I had white stuf coming out of my vagina and it was itchy kinda like a yeast infection. It was also very puffy. I applied itching cream (Monistat) and the puffiness went away. Right now the same day it's so red under my vagina hole and it itches like crazy I have small rash under it what could this be ?
