I had sex with a person that has gental herpes but no open sores, the condom broke, i washed very well am i still at a high risk of contracting it?

Low risk: In monogamous couples in whom one person has genital herpes due to HSV2, who have unprotected sex 2-3 times a week (and no sex during outbreaks), the transmission chance averages about once for every 1,000 exposures. That's roughly your risk from this single event. It's even lower if partner's herpes is HSV1. No exam or testing is needed if no symptoms (genital sores, pain) in the nest 7-10 days.
