My questions:

1. HSV-1 sheds asymptomatically about 3-4 days a year. Are these days consecutive? Does this shedding happen for everyone, every year? Is there any way to tell if I'm shedding (that is, does asymptomatic literally mean no signs)?

2. If I am shedding asymptomatically, what is my likelihood of giving HSV-1 to a partner through unprotected vaginal penetration or through them giving me oral sex? 

The days can be consecutive or they can be spread out.  It varies from person to person, honestly. We don't know that it happens for every person, every year, no.  And asymptomatic shedding means no signs are present of an outbreak, like the bump you described.

We actually don't have any data on HSV 1 transmission to a partner, either through intercourse or through receiving oral se.  Your report is the first one I've heard that clearly knows that transmitted HSV 1 through intercourse, though you did have symptoms when that happens.

We certainly know that transmission is unlikely through intercourse.

First, do you mean that you don't have any data at all on HSV-1 transmission via oral or vaginal sex, or no data for a partner who is asymptomatic? 

About 47% of the US population between 14 and 49 have HSV 1 infection.  

I think the reason for the lack of data is that HSV 2 is really the "problem child" of herpes - it recurs more genitally and it is the cause of about 40% of HIV infections .  HSV 1 is so common and normally doesn't cause a lot of issues genitally anyway.

I don't think there is any standard answer to your question.  Because shedding is so low with HSV 1, after being infected for a couple of years, and because so much of the population is infected already, perhaps not absolutely required like HSV 2
