I am a school nurse. An instructional assistant reported to me today that she has noticed when she is changing the pull up on a kindergartener (not potty-trained, yet) that his penile glans is different colors sometimes. She says that it is red sometimes and at other times different shades of purple sometimes darker than other times. I just observed a pull up change and, right now, it looks normal to me. It is flesh-colored at the end and purplish where the glans meets the shaft. Her concern is trauma. His pants and pull ups are not too tight. Could trauma of some sort cause this discoloration at this age or is it normal as it seems to be with older males (based on what I ve been reading here). Thanks
