If you can, talk to a doctor. There are drugs that can reduce how often you have outbreaks. I was taught that one was contagious for 3 days previous to a visible outbreak, and for 3 days after one, but it appears that new evidence suggests that herpes is both more widespread and more contagious.
You should always tell your potential sex partners that you have herpes before having sex with them. Some may decide that they can't deal with it, and choose not to have a sexual relationship with you. Others may decide that they want have a sexual relationship with you, but to reduce their chances of getting herpes, that they don't want to have sex, but are willing to use toys to have a fulfilling sex life. Or maybe your potential partner will already be infected, and you won't have to worry about it. While it's possible to "re-infect" each other, it is highly unlikely to change anything for either of you.
