Hello,
Since you were wearing a tight belt, so it can be due to compromised blood flow to the penis. It can also occur due to circulation blockage like in diabetes, smokers, having high cholesterol or peripheral vascular disease. Another possibility could be a mass that may be obstructing blood flow and vasospasm of the blood vessels.

You need to get certain investigation done which include ultrasound lower abdomen, angiographic study, plethysmography (the measurement of volume change in an organ or limb) or ultrasound to evaluate for circulatory disorders.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
