If I had to venture an educated guess on this, based on my own personal experience as a man and a son so far in life (yet to be a father to a boy so only speculation), but it would seem that men probably on some level "sniff" the kids to make sure they are "his" figuratively that is... as women are not interested in wasting time with men they don't want to be with for obviouse reasons of there is a window of time when they are able to "get a man, beget children, and get them raised" and waisting time just gets in the way and leads no where... men probably deep down as well, feel that if these are their offspring with will "look/be" like them as well... call it verification of resource expenditure. Since why would a man, who was seeking to pass on his genes (in the way of biological imparatives) seek to subvert his own reproduction for that of another man's with a woman that he then puts time into without the reward of having his children... he woudn't... hence when a man feels his children aren't like him he probably had a hard time relating to his sons... and males need (regardless of what feminists say) father/son bonds...

Today I think it's more a hold over from that kind of thinking that is just in the deep part of our intuitive side and kicks in at timem

On being Circumsized... personally I didn't mind it, didn't suffer from anything that was written above and personally perfer it... I have had great sex all my life, no issues with it and well... I had to kind of look at that list of horrible side effects and think "who made that up" my god, it's lucky I survived unscathed!

Seriously, no guy I know can even recall getting it done... it's like, don't remember... unless they were an adult (which I might add would be horrible, since it would take forever to heal, it would scar and be all horrible... so if your going to do it, do it at birth, if not, forget it, IT IS NOT an option anyone but a crazy man would do in adulthood, my god if a Vasectomy hurts, think about it...YIKE!)

anyway... mine is clean, senstive, cums fine, smells good, looks pretty and all that... never been embarassed in a mens shower or had a girl go "OMG what the hell is that!!" as some un-cut friends have had dating trauma over in HS and later... not to mention the fact they tend to hide it at every turn (locker rooms, and the whole deal... I can't think of anyone that ever really liked the idea of being un-cut, though I have seen guys when I was in the military and growing up and all... they just seemed to be uncomfortable all the time.

Just my two cents...

But for the record I wouldn't wait, either do it or don't, but doing it later... OMG NO... OUCH... readas - minor surgery becomes MAJOR surgery.
