Improvisation with whatever tools I have

The thought process goes as follow:

What cause jock itch?

Warm and moisture= fungus infection

Does it mean I could cure it fast with disinfectant?

What tools do I have that disinfect stuff?

-Alcohol

-toothpaste

-vinegar

-Mouthwash

Than I remembered someone had a blowjob, with a cooling effect blow job, I suspected it's either mouthwash or ice water.

But it's itching bad, so mouthwash is the way I choosed to be dead inside.
