4-S3xually Transmitted Diseases
The scary thing about STDs (and the reason you should get checked if you have unprotected s3x with someone you aren’t totally sure is STD-free) is that they often don’t have noticeable symptoms, says Dr. Hall. But one sign of many STDs is pain.
That can be more of a burning, inflamed kind of pain if you have genital herpes, a s3xually transmitted virus that causes breakouts of lesions on or around your v@gin@. Trichomoniasis, an STD caused by a parasite, may lead to redness and soreness of the genitals.
