One week ago, i had unprotected sex with my boyfriend who was a virgin and is uncircumsized. The sex was very rough, and i wasnt properly lubricated enough for it. Labia minora swelled up but has gotten back to normal size in a span of three days. I now have very fine small bumps on the inside of my labia minora near the vulva and it hurts a lot. My external genetalia has also been itching but it hurts to scratch it, so i dont. My vaginal discharge has a tint of yellow, it is odorless, but is thick, creamy, sometimes filmy, sometimes like cottage cheese or pus. He's my second partner, and i've been to the gyno before and have no STDs. What could this be?
