Scientifically faced facts state:
Ok, so here's the basics on the transmission of the herpes simplex virus (HSV). HSV comes in two common forms, and one not so common. You have HSV-2, the super contagious kind, but there is a light at the end of the tunnel. Like HSV-1 (characterized primarily by mouth/lip sores), HSV is spread when the fluid from your blisters contacts the mucous membrane or skin of another individual. It will always, always, ALWAYS be risky to have any form of sexual contact where your genitals come in contact with your partner. You less of a chance of transmitting HSV-2 if you are not experiencing an outbreak, but spread is still possible, and by all accounts probable. NOW, if you are limiting yourself to performing oral sex on your partner, the short answer is, NO, you will not transmit the disease, BUT there are variables to this answer. If your mouth/hands are in contact with your genitals at any time during sex with your partner (ie: you scrath your scrotum, then wipe away a snotty nose with your finger, you may have just transferred the virus to your face near your lips which will be in contact with your partners genitals.) This CAN spread the disease to your partner. The key: make sure that you aren't experiencing a breakout on your face if you are performing oral. If you are, wait until the breakout clears up completely PLUS 5 to 10 days to account for active latency. If you are experiencing a genital breakout, wash your hands frequently when coming in contact with others. Be smart. Be aware. Be safe.
