Hi there...it is very difficult to understand which part of the body you are referring to? Either the prepuce or the groin area? If your prepuce is tight, then you might be having phimosis. Kindly consult a general surgeon for that. They will advice you regarding that. You might have to get circumcision done. But do not self medicate with any creams, especially steroids creams. Skin in thise areas will be very sensitive. If you apply steroids it will cause atrophy and further side effects.
