15. Sexually Transmitted Diseases

Sexually Transmitted Infections (STDs), or sexually transmitted diseases (STIs), are sexually transmitted illnesses from one individual to another. Contact is usually vaginal, oral, or anal. But they can sometimes be spread by other physical contact. Usually since some STDs, such as herpes and HPV, are spread through skin-to-skin contact.
Sexually Transmitted Contaminations (STDs) - or sexually transmitted infections (STIs) - are usually contracted through sexual contact. Bacteria, germs or parasites that cause STIs can be transmitted to another person through the blood, semen, or vagina and other body fluids.
