I'm kind of curious how your son accidentally touched your vaginal area. Did you not have underwear on? You are saying you have HSV 1 on your genitals? Or you have HSV 1 like most people simply on your mouth? Confused.
Like Dave said even if you had hsv1 on the genitials and he touched it it takes a rubbing in motion to transfer and the fingers are thick non preferred areas of infection. Even licking his finger after would present no real risk
Hi if you have hsc1 its most likly oral so him touching your vaginal area he could not get hsv1. even if you have it vaginal he cant get it by touching.
