Hi. HSV-I can infect both oral and genital mucosa. Although before the change of sexual practices in 90's it was the most common cause of Oro-labial herpes and
HSV-2 was the commonest cause of
Genital herpes but now it has all changed due to change in sexual practices and oro-labial and genital herpes can be caused by any type of HSV (I or II).
Herpes gets transmitted as a result of intimate contact be it Peno-vaginal sex, cunnilingus(
oral sex performed by a female) or fellatio(oral sex performed by male).
Since you got genital herpes by fellatio (oral sex performed by male partner). So you can further transmit infection to your boyfriend via Peno-vaginal sex since he still does'nt have genital herpes.
Cunnilngus (oral sex performed by female partner) is safer since you don't have labial herpes and thus cannot transmit it to your boyfriend.
If he performs oral sex on you he will get reinfected and can develop a clinical episode of herpes.
Both of you have HSV-I type infection, so theoritically both of you can still get HSV-II type infection from outside.
Once infected Herpes will stay in the
nerve ganglion for your entire life and their is no way to eliminate it permanently.
Antiviral pills can be taken for episodic treatment just for the episode(5 days) or for suppressive treatment(1 year) if their are frequent relapses of genital or labial herpes causing considerable morbidity.
I would advice that you visit a
dermatologist and clarify further if you have any doubts.
take care
