Red around 4 month olds penis

just noticed befor that my 4 month old is red around the tip of his penis, it's not bothering him when he pees and there's no blood or puss coming out etc, anyone know what it could be? If it is just nappy rash would it be ok to put sudocream on it? Or should I just leave it alone and see if it heals on its own https://100001.onl/ https://1921681254.mx/?
