Question for Parents with boys - have you experienced a frenulum?

Just a quick question as i am pretty concerned, my little boy still has a frenulum on his penis.. and yes he has been circumcised, wierd i know. I have never seen one before my husband doesn't have one either did my x. Why didn't they remove it when they did his little circumcision. My question is?

Does your boy have a frenulum still?

Do you think i should get it removed?
