We don't have actual stats for this - hsv1 transmission hasn't been studied this way, but you had protected oral, and oral sex is lower risk than genital sex. I wouldn't worry about herpes - or anything - since you used a condom.
Also, since you used a condom, symptoms would likely be on your skin and not inside your urethra.
How's your hydration? Drinking enough water? Try increasing your water (reasonable levels, don't overdo it - that's a whole other set of problems), and lay off the caffeine and alcohol and see if that helps.
