Can she get herpes from oral sex?

OK my ex-bestfriend had sex with a boy who use to have herpis and he eat girls out can she get a disease to oh also he ate her out as well

If he had oral herpes (the same germ as genital herpes, but in the mouth or throat) then he can spread it through oral se*x. If his herpes was genital, then he doesn't automatically get the oral form.

Definately possible.

Yes, she can. No one can used to have Herpes. Herpes is an incurable disease right now, so once you have it, you have it. If he had herpes in his mouth and ate her, she can have herpes on her vaginal region. If he had herpes on his fingers and fingered her, she can have herpes on her vaginal region. Herpes is a disease that hides under the skin, something triggers it to come out, then it disappears under your skin again, until it is triggered again. 70 percent of people who had herpes don't know it because they have no signs or symptoms. Tell your friend to get checked out.
