If I had just had a recurring outbreak and took antivirals and everything was cleared up, how likely would it for another outbreak to occur right after?
Unlikely but not impossible. And unless your OB did a swab test if the area in question, it isn’t possible to know what this was, honestly.
It seems like sex is one of my triggers, but could a recurring outbreak even form that quickly after sex? Whenever I had the recurring outbreak I had noticeable tingling symptoms leading up to it and during the outbreak.
How likely is it to transmit ghsv1 to a negative male partner if this is an active outbreak?
well, if you are saying you had intercourse with someone while you had an HSV 1 lesion, the risk is certainly present UNLESS this person also has HSV 1, which half the population has. Did you discuss it with them?
