Sexual conditions, such as STDs and sexual problems, need a medical evaluation and treatment. Frequently, there are no STD symptoms, although there's sometimes a discharge from the vagina or the penis and burning or pain during urination. Doctors use STD tests to diagnose sexually transmitted diseases such as chlamydia, gonorrhea, syphilis, and trichomoniasis. Whereas STD treatment can help resolve these sexual conditions, practicing safe sex can prevent STDs.
