I started my period 5 days ago. I had sex maybe 2 month ago (it was unprotected). I am 19 and my periods have been irregular for the past year. I have noticed itching around my vagina, I ve never had that before. So I got curious and I looked. I guess my vagina looks more red than pink and I noticed that there were smooth bumps. But they weren t pimples, warts, or skin tags, just smooth bumps, not really noticeable. and it does itch and then it kinda was a struggle to get the tampon in the other day, like skin was in the way. But I m afraid I have a STD!
