Sexually transmitted diseases (STDs) — or sexually transmitted infections (STIs) — are generally acquired by sexual contact. The organisms (bacteria, viruses or parasites) that cause sexually transmitted diseases may pass from person to person in blood, semen, or vaginal and other bodily fluids.
(STDs) or sexually transmitted infections (STIs) can have a range of signs and symptoms, including no symptoms. That's why they may go unnoticed until complications occur or a partner is diagnosed. Signs and symptoms that might indicate an STI include:
Sores or bumps on the genitals or in the oral or rectal area
Painful or burning urination
Discharge from the penis
Unusual or odd-smelling vaginal discharge
Unusual vaginal bleeding
Pain during sex
Sore, swollen lymph nodes, particularly in the groin but sometimes more widespread
