MYTH #3:

You would know if you had syphilis.

FACT#3: 

Like all STIs syphilis can have no symptoms, or you might not notice them. People can have syphilis for a long time and not know it. It may not be obvious if your sexual partner has syphilis because syphilis sores can be hidden in the vagina, anus, under the foreskin of the penis, or in the mouth.
