Flaky/scaly sounds like jock itch, but you really need to see a doc, and you still need to abstain until your symptoms are gone.
You can share fungal infections with partners, and then you end up ping-ponging it back and forth, and that's no fun.

The affected area is on my genitals. i may have worded it wrong but the area is more like jock itch than a rash. does that make a difference? It itches so when i scratch it sometimes it becomes raw because the skin gets dry and flakes/scales off revealing the lower layer of skin. it usually doesnt bleed but i am still worried that something could have gotten through.
Well, your chances are increased if the rash was in the genital area, but you did use a condom, so that helps counter that.
You shouldn't ever have sex when you have a rash or any other symptoms genitally. You could be passing something to the other person.
