Probability of spreading HSV1 through oral sex

I have had HSV1 orally since I was a child and am aware that most of the population has it, and I know not to make contact/share food items etc. when I have an outbreak. However I never knew that it could be spread to the genitals through oral sex.
I have been in a monogamous relationship for 2years now and have had unprotected oral sex a few times, non of which I can recall having an active outbreak. The last time we have had oral sex was over two weeks ago and they have never shown any signs of infection, is it okay to assume they are not infected?
And what is the typical duration of an active HSV1 oral outbreak so I know when to completely avoid contact to be more safe?

Does he have oral cold sores? This is the biggest factor of all.

Most people experience symptoms within 7 days.

But look, he along with most people without HSV1 do not particularly care. Most of their partners have HSV1 and what is the alternative... no oral sex... most of  them say 'no way, I'll take the risk' which is as it should be!

If he were to become infected, how long before symptoms show?
I have read many different opinions, some say 2-7days or as long as 2-20days before symptoms show, also that some people don't show symptoms at all... But Since it has been over two weeks im hopeful that we're in the clear?

If your partner has oral cold sores then there is no practical risk of transmission.

Otherwise the chances are do not exceed 1 in 200 per episode and probably more like 1 in 1000 if you avoid outbreaks.

It depends, but a cold sore cycle is on the order of 7-10 days.
