Bro, if it's not too personal, just why did you choose to have your boys circumcised?  

ever heard that if circumcised you can last longer than man who uncircumcised ?

Well, I am circumcised so they would be just like me!  LOL... JK... I just figured it would be cleaner for them in the future.  I really put a lot of thought into it before my first son was born.  I always believed that those who are not circumcised have better sex since the sensitive nerves of the head is always protected until it is ready to perform.  Us circumcised guys are always having our heads rubbed by our underwear and whatnot when we walk or whatever we do, therefore desensitizing the sensitive nerves and perhaps even building a thicker layer of skin over the head.  However, if this is true, then circumcised penises should theoretically last longer because of the loss of sensation.  But when it really came down to it, it was hygiene.  And yes, I know if uncircumcised penises are washed properly daily, it is not a problem but it's a choice I made for my first boy.  The next two boys just basically followed suit and the wife and I did not put any more thought into subject.  As for the having sex part, considering that I am circumcised (and not tootin' my own horn) and I am still a fuckin' sex machine! Literally!  LOL...  I doubt my boys will have any problems with getting circumcised.  I think more adults who are circumcised would not want to have it any other way, on the other hand uncircumcised men tend to have the snip snip for either hygiene reasons, the look or simply necessary in the case of those who have elephant trunks encasing their dicks.  Make sense?  Doesn't to me, but I hope it does for you! LOL...
