Sorry if this is tmi?

I started working at this restaurant two weeks ago. I started talking to my coworker, well about 3-4 days ago I found out that I have a std that will be stuck with me for the rest of my life... I'm 18 if that matters? Anyways we haven't been talking long at all. But his been talking freaky to me and I always tell him to take things REALLY SLOW. His a little older than me. I like him, but I'm not sure if this is the right time for us. He does tattoos and later today his gonna give me one... what should I do??  I'm really scared and I even cried to the nurses about this std called, "herpes" ... i need advice when is the best time I should tell him or just let him go?? Please comment... I haven't really told family only 4 people know.. help... I'm on medicine...
