Boy mamas

All my circumcised boy mamas, I have a question for you.

My LO is 10w today and his little penis has been tucked inside like he's cold, even when he isn't. I've pushed to pop it out to clean it and it seems red and the head is kinda purple. I'm a FTM so I'm a little worried. I put A&D on it incase it is a rash. But is anyone else experiencing this? Any advice? Help pls.
