People with STDs can spread them to their sex partners. STDs are serious. If left untreated, different STDs can ?cause blindness, cause infertility, give you painful and embarrassing sores, make it easier for you to get more serious diseases like HIV/AIDS, or can even cause death.
And they hurt more than just you and your partner. A woman can pass an STD on to her baby during childbirth.
