It is NOT Herpes!
Believe me, it is not. Genital Herpes in not like that. An outbreak of Herpes is nothing more than like having a cold sore on your genitals. It is not the end of the world either. It is just an inconvenience, and you cannot get it from a person that does not have it. It is also not all over, but just in basically one spot. It may consist of a few tiny blisters, but they are in one place and not all over. And, they are never in your mouth and your genitals at the same time.
You got something from the rug-rats, which is far more likely since kids can carry all kinds of crap that they get from their playmates.
