Yes, I would guess that you acquired HSV 2 a while ago and yes, that does protect generally against HSV 1 infection.
There is no way to know for certain where your HSV 2 infection is, but the statistics suggest that there is a 95% chance it is at least genital (could also be oral but not all that likely). If I were you, I would assume it is genital and behave that way – sounds like you are already on that track.
Yes, five days lead time for suppression to be fully effective.
And yes, to the best of our ability to know, I believe you don’t have HSV 1. We do not yet know the exact sensitivity of the western blot for HSV 1.
I would say it is completely normal for your attitudes about sex to change now that you know you have herpes. But I suspect you will “bounce back” once you’ve had a bit more experience with this and you continue to have experiences with people who are willing to take a small risk of transmission. I would also say that you might suggest that partners be tested to see if they are already positive or not. If you are having sex with someone else who is positive, there will be no concerns at all about transmission.
