sore got healed and not ulcerated or burning now in 1 day after applying clotrimazole cream( anti fungal) and coconut oil.. I think its a groin chafing/ jock itch happened

i have similarities looking for answers as well… pics attatched, stings when I pee & irritable if touched or rubbed..

pictures are blurry and cant see anything

I do not feel burning sensation while peeing.. Most of the times it’s fungal infection CANDIDA.. If you are sexually active or had unprotected oral /vaginal.. Kindly take STI test

Though i had protected sex and protected oral thing, worried about STD now.
i got these skin redness, white flakes, raw skin in skin fold groin region and caused burning to touch.. I cleaned for 2 days and got healed completely by now..
