"Well that's why some things need to be discussed very early in the relationship."
Please don't take this wrong, but this sentence made me laugh. I'm just picturing a conversation at a bar:
man: "Hi, what's your sign?"
woman: "Aries. What's yours?"
man: "Taurus. Wanna go out sometime?"
woman: "Maybe. Are you circumcised?"
I'm just having a hard time imagining how such a discussion taking place before two people are already semi-committed to each other. I must be old-fashioned.
As to the substance, now that the little boy is already 2 1/2, such an irreversible procedure should not be done and he can decide for himself when he's an adult.
In this day and age, a girl needs to make it quite clear to guys what she will and will not do in a relationship. A guy should not waste a girl's time if he is going to dump her over sex.
