I'm new to the whole herpes thing myself only found out I have it 2 days ago an I'm still absolutely gutted.
But I have done a fair amount of research and from what I've found so far is that, HVS T1 is different from HVS T2 and that if you have HVS T1 you an't give it to someone via sexual contact. as HVS T1 is oral herpes.
If you were to go down on someone then yes you could give them the HVS T2 or if you were to kiss/makeout then you could give someone HVS T1.
But remember during the process of having Herpes it's frequent spreading period is during outbreaks, that's not to say you can't give to someone when you aren't having breakouts because you can.
but the chances are a lot smaller; I still haven't been able to come to terms with the fact that I have HVS T2 and honestly havent been put in the situation where I have to tell a potential partner.
But I can tell you this, put yourself in his position and him in yours, would you want him to tell you he has herpes prior starting anything serious with him?
Would you want to know if there's a chance you could catch this virus, or would you rather find out weeks or months later by yourself that he gave you a virus and didn't tell me or warn you prior.
That's the best answer in terms of what you should do.
If you have HVS T2 then yes a condom becomes basically mandatory, unless you're trying to concieve in which you then should wait till you have no outbreaks or any signs of up coming outbreaks.
This goes the same with HVS T1 try keep kissing and making out to a minimum, and none what's so ever if outbreaks are upcoming or are there.
Hope this advice helps, I'm sorry to hear you have this horrible disease as well.
I'm sytill absolutely torn from this. Good Luck.
