Hello @oms2001. I was about to post a discussion with the same question.
I was diagnosed last week with G-HSV1 as well. I'm in a relationship but my partner is currently waiting on his results. In the event he is negative for HSV I was also curious about the future of our sex-life. Condoms are planned for but unsure the risk factor for performing oral sex on each other.
I have read in other forums of couples where only one of them is +, the other is -, yet oral sex is still given without protection? I think this was the case for a woman who was HSV2+ (since this type is more prevalent genitally and cannot be transmitted to become oral HSV...?). But for the case of HSV1 I'm completely unsure.
With a new diagnosis of Genital HSV I am making appropriate life style adjustments and, like you, am trying to get as much information on the risks of transmission and my options going forward with my partner/ any future partner.
Hope we both get insight into this particular topic revolving around oral sex practices with a G-HSV1 Dx, I have found searching for answers online very difficult regarding this specifically.
