I have type 1 genitally also. Think I caught it from an ex boyfriend who went down there with a cold sore when I was 17. A few weeks later I got my first outbreak which was horrendous, and subsequent ones have all occurred when my immune system is low and have been very mild thankfully.
Here are some facts -
Once you have Herpes, it will 'live' in your nerve endings and may re-activate again. You cannot ever get rid of it completely, but good diet, lifestyle and vitamins can much reduce the chances of another outbreak .
Don't be ashamed, a hell of a lot of the population actually carry this virus, however most don't get an outbreak at all, so they won't even know they have it.
A person who has never had a cold sore on their mouth is more likely to show symptoms if they catch it genitally.
The virus is highly infectious during an actual outbreak, and even when not during an outbreak viral shedding can occur which can infect a partner, although the risk of infection with no actual sores is very low, and even more so the longer you have had the virus.
You can take anti-virals daily until you are ready to tell your new partner, which will reduce the risk of him contracting it to pretty much zero
. Wouldn't advocate taking them for years though, just until you feel comfortable telling him. Go to your local gum clinic or GP.
I was scared of telling my current DP of 5 years about 4 months in I told him after the constant anti-virals to prevent transmission were giving me sore stomachs, terrified of his reaction, but he just said "oh yeah, i think i may have had a spot looking like a cold sore down there once before - don't worry about it" I was terrified I would pass it to him but he must have a good immune system as he has never had an outbreak yet, and I don't take the anti-virals.
