STD!?

Okay so I recently had sex, my a vagina is kinda

small so I tend to tell people not to be so rough

when we're having sex. He was a bit rough

though and notice after sex I had a few tears in

the area that separates your vagina from your

anus. Then it got kind of irritated throughout the

week. Then I seen this, I always keep myself

safe during sex. And I never had an STD so I'm

freaking out right now. I even checked my

discharge to see if there's anything abnormal

going on. It doesn't smell or anything and

there's not a color change at all. Even my clitoris

is a bit irritated, please someone help.
