Seems you are suffering from fungal infection
. The fungal infection in the groin region is usually itchy and when you scrab it, they will ooze sometimes may bleed a bit also. It is usually dark in color with raised margins. Look whether you are diabetic or not by checking your blood sugar levels. You can use anti-fungal creams (without steriods is better) twice or thrice a day for nearly 2 weeks, after bath. Keeping the part dry will help you avoid its recurrence.
Get well soon,
