Hi, I am 20 years of age. I currently lost my virginity at the end of the summer near the beginning of August. My partner is clean, and we had unprotected sex. I discovered that a few weeks later, I will say 4-5 weeks later, I started to feel a itch. It was no smell, no discharge, everything seemed normal. I checked myself with a mirror, and i saw little tiny bumps located near the opening of my vag on the inner flap. What does this mean? I am fine, no yeast infection or signs of std. Can it be from the friction of the penis entering the vagina?
