Who is more mature when it comes to relationship? Men or Women?

I'm not sure I'd choose one over the other, both men and women tend to be hormone driven in relationships which makes everyone tend toward childishness as a rule but there are exceptions. If I had to choose one, I would pick women because they have a more extensive corpus collosum (the connection between right and left hemispheres of the brain) which seems to cause a better connection between emotional and analytical thinking. Sorry fellas, I don't mean to betray the brotherhood but it's true, women tend to be the glue that holds societies together through emotional bonding. But I do hold to my original statement, both tend toward being silly in romantic relationships, it's not ALWAYS the case and certainly some individuals of both genders handle relationships better than most people.

man and woman are both mature in a relationship but do woman mature first in such an early age, men mature in the latter part. but different factors make them mature early, such as his environment, relationship he have, age, culture..

For me it depends, we should not look only in one, two three or more. But all aspect, remember that money also affect certain maturity in relationship.
