I got genital herpes a few years ago, and I'm reasonabley sure it was from owo, as thats the only unprotected sex I ever had. The problem with herpes is that it can't be cured, and you have it for life. If you're lucky you don't get many outbreaks, but I get an outbreak roughly every 4 months, but on occasion I've had two outbreaks only a few weeks apart.
Its a pain obviously, and I have to make sure I don't have sexual contact with anyone if I feel an outbreak coming on, or during one (obviously) and until it's completely healed up. Lately I've been going for massage and hr, which gives protection for me and the SP.
