I know you asked this a long time ago but I thought i would give my opinion anyway.....
right now it may not seem like a big deal- but in the long run, he may have problems not being circumsized (when he is older- teenager and up...) you definitely need to keep it clean because if you dont he can get build up and his little part can get infected inside-
my nephew got circumsized when he was born but it was done wrong i guess-there was too much skin still--- and he got an infection then he had to get another circumcision done before he was one!- my brother and his wife were so upset over this but I would suggest to get it done.
