first of all, if you were forced into it then it's rape and you should report it.

second, anything you can get on your genitals, you can get on your mouth/in your throat. it does make it easier to transmit when you have an open wound because the viruses can get into your blood stream easier but it's still pretty difficult to transmit stuff that way. i have had cold sores since I was 12 and have gotten oral sex from guys who had cold sores and none of them (and me neither) have ever gotten genital herpes from it. there is something about the 2 strains (oral and genital) that make them prefer those places that genital is less like to occur on your mouth and vise versa.

if youre really concerned you should see a doctor and get tested. a lot of places do anonymous testing for stds also if youre worried about being embarrassed or anything.
