it is nothing to be worried about, realy. Doctor is so proffessional , you lay on a bed on your left side, pull knees up to your chest and pull your pants down at the back. 10 seconds later, pull them back up. You are never naked in front of the doctor. Definately does not hurt, and may help a diagnosis. It is not though required. My DRE was declared normal, not enlarged and felt fine, but my PSA came back high, and was promptly sent off for a biopsy, which was positive.
All the best with the results. If the PSA is high, it looks like you will have discovered it early, which is good.
