I repeat: Your discharge is not due to herpes. Go get checked out for NGU, chlamydia, and other STDs.
The chance of transmitted genital HSV-1 to your partner is very low, maybe zero.

Thanks Dr. In a situation like this one where we had sex with a condom, and the suspected discharge being the only visible sign or symptom, what would be the likelihood of my gf getting infected with hsv-1 genitally?
Your genital HSV-1 infection sounds typical: Many persons have only the initial outbreak without any recurrences at all (unlike HSV-2). Your dishcarge probably is not due to herpes. It sounds like you might have urethritis, such as chlamydia, or nonchlamydial, nongonococcal urethritis (NGU), or conceivably gonorrhea. Or you might just be seeing residual sexual secretions, since apparently you notice the problem only after sex. But herpes rarely causes discharge without sores or pain and I doubt that's the problem. If the symptom continues, and especially if you notice discharge independent of recent sex, see a health care provider.
