Generallly low risk, bacterial infections probably being the highest(although I stress not likely), with NGU being the most likely. NGU, Gon, syphilis, and hsv, and hpv would all be a possiblilty. However stastically speaking all except NGU would be very very very unlikely.
Because you are married, I'd recommend testing at the appropriate times
Thanks joe. When do I test for what std?
