Ok I'm going to be Buzz Killington here... and break it down technically and scientifically!
I learned in college psychology 101 that women are designed to nest and nurture but men are designed to spread their DNA everywhere. In other words... this is the reason women have one time a month they can get pregnant and only certain times a month they are "in the mood" and a 9 month gestation for one little baby and men on the other hand.. lol each "occurence" has millions of "little guys" in it and some guys have a libido that allows for some pretty hefty promiscuity. ewwww!
It's also why you see so many single moms working hard at their little family and so many dead-beat dads that ran away to go party

Of course there's lots of people who don't fit either stereotype (runaway mom, stay at home loyal dad) but yeah this is the general rule among human psychology.
Now I could be wrong, but I think this feeds into what you said.
Men can be more impulsive and women can be more logical.
Not always. But it definitely seems like 9 times out of 10, a guy will notice a pretty girl and will just HAVE to talk to her (if he's a gentleman) or take her home (if he's a bar guy) where as my girlfriends, they go through a long list why they will or won't talk to someone based on his personality or his history with the other ladies or whatever and looks are important but not #1. Then they shyly wait for him to notice them. lol.
