I found this to answer your incidence question -
"In Australia it is estimated that three-quarters of Australian adults are infected with HSV1, and one in ten adults with HSV2. Women are more likely to be infected with HSV2 than men."
Even if your partner doesn't have hsv1, the chances of you transmitting from your genitals are as close to zero as it gets.
You never did say why you thought you got this orally as well as genitally, but if you are concerned about transmitting it, talk to your partner. Ask if they've ever had a cold sore. Remember that an STD conversation is still needed - there are other things that you need to know if your partner has. Talking about hsv1 can be part of that talk.
