6. Pubic Lice
“Crabs” are a form of lice that live on the hair in the genital area and occasionally on other course-haired areas of the body, such as the armpits or the eyebrows. They are usually spread by sexual contact, although they also can be transmitted by infested linens and clothing. Symptoms include itching in the genital area and visible lice or eggs. You should know that crab lice are not the same as head lice, and that they almost never infest the hair on the head. And the rumor that you have to shave off all your pubic hair if you get infected — that simply isn’t true.
