Someone with 20 blisters is likely having a true primary. In pregnancy sometimes, we see people having recurrences that look like primary infections, but usually not in people whose immune system is fully intact, like you.
It will take you a while to be able to sort out what are herpes sensations and what are not. One way to sort that out is to have any suspicious things swab tested to see if there is virus present.
With HSV 1 genital infection, you are unlikely to experience many recurrences at all. But you might have more during that first year of infection as your immune system gets used to handling the virus.
