Hey! Sorry you're going through this but I will try to answer your questions to the best of my knowledge! :)
1. It's not likely that you contracted it from your Brazilian wax. Asymptomatic shedding occurs around the infected area in which I'm guessing she didn't have hand herpes.
2. Genital-to-genital HSV-1 isn't as common as oral-to-genital. Since HSV-1 typically prefers the mouth area, it is less likely to pass it on to him genitally(but still possible). It is also less likely for a woman to pass it to a man, than it is for a man to pass it to a woman. However, if you do transmit it to your partner, you would be passing to him whichever type you have as well.
3. Yes. Even if you are all cleared up, there is no telling when asymptomatic shedding may occur. In which, if it does, it is more likely that you will pass it to him orally.
4. Outbreaks for genital hsv-1 are less common than outbreaks for genital hsv-2 and oral hsv-1. Recurrences after the primary outbreak are few to none and not nearly as aggressive. A swab test is the most accurate of them all when it comes to HSV. If there is a present sore, a swab test can determine which type it is, whether it's type 1 or 2. Blood tests are usually for the people who have no symptoms present.
5. It is possible you could have gotten it from your current partner or your previous partners. HSV can lie dormant in the body for yearssss. So it's nearly impossible to pinpoint who, when, or where you may have contracted it from, unless someone you were intimate with knew they had it.
Hope that helped you some! :)
