It's just not easy for a surgeon to circumcise with perfect tightness. I've heard of some doctors inducing erections during the procedure so they can better see what it will look like
Erect but this can have several issues so it's not normally done. Even just making it a little tighter than it should be will negatively impact your
Erection, i.e. making it shorter. It's difficult even for s
ed and experienced surgeons to determine exactly how much skin should be removed. So in general, they error on the side of caution and leave it a little loose. Like I've said several times, the average
Urologist at your local hospital won't listen to your aesthetic wishes. They aren't trained to do that.
But in general,
Circumcision has been found to cause no loss in length.
