Telling ppl you have it...

I've posted on here about the terrible time I'm having excepting that I have herpes. And every time I post there's always those people saying how they tell potential partners RIGHT AWAY that they have it even before they know if the person is there to stay. I see why that may be the way to do it for some but how do you trust these random dates with that information?? I'm casually talking to a guy we've been on 2 he's definitely not the one... just not really my type but I can't even imagine having to tell him or anyone that I've only been on a few dates with. That's a secret to me. I haven't told anyone and I don't think I will unless I know 100% that he most likely will be the one for me... but on the flip what if I think he's the one then I finally tell him and he runs... ugh I hate living with this I feel like an outsider in my own body..
