Noticed prodrome after sex.

Hi all. It's been a long time since I've posted here! Long story short I have hsv2 (found out 5 years ago) and I'm in a relationship. I take daily suppressive therapy and haven't had an outbreak in over two years, and have only experienced prodromes a couple times.

One of those times is now. My boyfriend and I don't use condoms. We very briefly had sex yesterday (TMI it was brief because I thought my period was over... it was not!) So after about 13 seconds of sex, we get into the shower and wash off. I noticed after I had a little tingly feeling, and today it feels like prodrome. Tingly, sensitive skin. I took my daily dose of Valtrex and they already seem to be nearly gone, a little more than 24 hours later.

So my question is what everyone in a relationship wants to know, what are the chances that I passed the virus on to him?
