What are the signs I have a STD?

While some STIs/STDs can have varying symptoms, most are considered asymptomatic (no noticeable symptoms or signs) in their earliest stages. However, STIs/STDs can still be spread and cause damage to the body when there are no outward signs of an active infection. It is important to be screened if you have had unprotected sexual activity of any kind (vaginal, oral, or anal).
