Should the guy or the girl "wear the pants in the relationship"?

I have just been wondering lately about this. Not only in terms of sex, but, in terms of who is head of the house, who has the final say in what happens, ect. Things like do you think the male should always have the last say? Or Who chooses what postion? Or who punishes the kids when they need it, anything like that…. Sometimes I enjoy being in control and making the guy submit to me (hehehe take it anyway you’d like (:) but sometimes I just feel the need to be shown who is boss lol. Hehe its fun.
