I'm sorry, I don't know how to interpret "divet" (I think spelling is divot, but I'm not a golfer!). And I don't know if "feels raw" means it IS raw, i.e. red and sore? You also don't say anything about whether you or your wife are at risk for STD, but the vague description you give doesn't like STD. Maybe a yeast infection?? Did you try the antifungal cream? The standard advice applies here: see a health care provider.
Rashes on the scrotum rarely are STD, and the response to antifungal cream indictes it was jock itch.
Good luck-- HHH, MD
