Your doctor said to have it done. That clinches it. But many doctors are totally bias against the natural foreskin. If a doctor simply assumes that circumcision will be done, that automatic conclusion has a strong influence on many parents. Even when people do attempt to learn the other side from their doctor, if he's FOR circumcision, the information he gives is likely to be colored or inaccurate.
Sex is better for both parties with a circumcised penis.
It also looks better. Maybe you've never seen an adult male intact or just aren't used to seeing the foreskin. We prefer what's familiar. That doesn't make it better. My religion requires it.
