Also, if YOU have the simplex, and you just so happened to play with yourself after you had recently touched your mouth, or even had to change a tampon, (in some way getting your saliva or touched
the area
of your
mouth then used
the same part
of your hand on yourself.) you may have given it to yourself.
Away from the scaring: Did you do something lately, like change a tampon, and maybe catch the edge of your lip (labia) in the edge of the applicator, as you were inserting a new tampon?
