I've just found out my 20 year old gay son has herpes. I'm not sure exactly what type but I think it's genital herpes. His taking Valaciclovir 500mg one tablet twice a day. My concern is that I have many younger children and could they catch it by sharing a towel or any other type of contact? How did he catch genital herpes, was it through anal sex or oral sex? Im worried for my son and younger children. Will my son have herpes for the rest of his life? Thank you
