My DH and I have been talking about this since we got pregnant and TBH still haven't reached a decision... But I do want to say that I think getting your son circumcised because his father wants his penis to look like his, really isn't the most rational reasoning. This is because:
- the childs penis will still look different to their fathers ? unless of course your little boy has pubic hair and is oversized.
- the child is probably more concerned with having a penis that looks like their peers, rather than their fathers (lets face it kids do compare these things).

Hope I haven't offended anyone, this is just my opinion.
