Sexually transmitted diseases (STDs) or sexually transmitted infections (STIs) are usually acquired through sexual contact. The bacteria, viruses, or parasites that cause sexually transmitted diseases can be transmitted from person to person through blood, semen, or vaginal fluids and other body fluids. Sexually transmitted diseases (STDs) or sexually transmitted infections (STIs) are infections that are transmitted from one person to another through sexual contact. The contact is usually vaginal, oral, or anal.
But sometimes they can be transmitted through other intimate physical contact. This is because some STDs, such as herpes and HPV, are transmitted through skin-to-skin contact. STDs are transmitted from person to person through vaginal, oral and anal sex. They can also be transmitted through intimate physical contact, such as intense caressing, although this is not very common.
