Unfortunately, we don't have transmission studies on ghsv1 like we do ghsv2, which is why you were unable to find anything.
We do know shedding rates, though:
Shedding rates: (and you can find all this in the herpes handbook - https://westoverheights.com/herpes/the-updated-herpes-handbook/)
HSV 2 genital 15-30% of days evaluated
HSV 1 genital 3-5% of days evaluated
HSV 1 oral 25% of days evaluated
HSV 2 oral 1% of days evaluated
The stats you have for ghsv2 transmission from female to male are correct (and are for the course of a year, assuming sex 2-3x a week), so if you're a math wizard (I am not), maybe you can extrapolate these into some kind of risk numbers.
Does your partner have hsv1 already, if you have one? If your partner already has hsv1, either orally or genitally, he can't get it from you as he has antibodies that will protect him from a new hsv1 infection. You can't give someone what they already have.
We know that ghsv1 rarely transmits. You'll know in time how frequent your outbreaks are - and in general, they are less frequent than ghsv2 outbreaks - so that may factor into your treatment decision.
Suppression isn't recommended for ghsv1 as it is for ghsv2 to reduce transmission. Many take it anyway for peace of mind. It's up to you and your partner. Personally, I probably wouldn't take it for transmission, but if I got frequent outbreaks, I'd take it for that. That's me, though, and you have to make the decision that's best for you. There's no right or wrong.
