Hi there ~
I understand your concerns. The rashes on your scrotum
seem like herpes
genitalis and it seems like you also have a problem with genital hygiene. I believe keeping the area clean and dry for about a week as well as consulting a doctor to find out what the lesions are (a physical examination is necessary) would be the way to go. I wish you all the very best in your recovery.
I hope this helps. Take care and have a lovely day!
