Thank you for asking your query at DoctorSpring.
Your risk of infecting the partner is not very high. But still there is a risk. (as you have rightly pointed out). It is difficult to quantify the risk, but think about these -
There is a good chance that you are not infective now.
There is also chance that you might not transmit the infection in the process.
There is chance that your partner is already infected (Upto 50% of adult population can have Herpes infection even without them knowing), so you are not risking him.
And finally there is a chance that he will get infected, but never manifest the disease. (Upto 20%)
So I would say odds are in your favours and you should not worry about this. Do take antiviral (Valtrex) for couple more days, if you have the prescription. This will reduce the viral shedding if any. There is no reason to worry. Go ahead and Wish you all the best in your relationship.
Hope this helps
