I was cuddling with this guy and then he said that he had syphilis, but was treated back in February. I was shocked because I saw his arms and he had some red marks which scared me. we didn't kiss or have any form of sex. Just cuddling and he kept rubbing his hand rubbing around my body. I don't have any open sores or cuts on my body. Should I be worried if I caught syphilis this way?
