I'm fourteen and I've been sexually active since last November, me and my partner have been tested for STD's and we both came out negative.- :]

Lately I've noticed in my Labia areas that it's red, swollen, and itchy.
When I pee it doesn't burn or anything, it just hurts..

This whole ordeal has been going on and off for about 2 months.

I've tried Vagisil to see if it was a yeast infection but nothing fixed it, what could this possibly be?

Not to mention, [this is VERY embaressing] inside of my vagina like 3 inches in there's a large bump. It hurts to touch it, and it moves. I was just wondering, could this just be a fecal matter or something I need a doctor to look at?

Help me please, .
