I don’t use Reddit as my source of medical information and neither should you. A lone vesicle from Whitlow will not be there permanently.
Did you have a swab test that was positive from the area of the finger skin changes, is that how you know it is whitlow? I think if you fully cover the lesion and perhaps use a glove, you should not be worried to go back to the gym or have sex with your partner.
I”m not certain I understand the question about the vesicle shedding?
