herpes causes painful Blisters and then become ulcers, spread easily to other places.. Syphillis / LGV cause painless Chancre with raised border and mostly it goes unnoticed

Chancroid cause painful ulcers..

groin chafing or groin fiction cause skin redness / blisters / sores and it gets healed if you apply antifungal cream or oinment

Ps: Ulcers takes time to heal

I did some research on std

so what do you think it may be?

Would you have any other pictures? There a tad bit blurry
Best Regards
