I can only backseat drive on this question. It most definitely varies on the couple and the individuals in the couple as well as kismet, fate, or destiny, in my view.
Everyone at that point has been socialized by family, extended family, cultures and sub-cultures. In my limited view it is like growing physically one day you are about 3'-6" then suddenly you are 5'-4" or 6'-6". Like that spurt of growth as an adolescent a spurt of growth 'will' occur from a holistic - body, mind, spirit, view during college days. Then values comes into play during this growth spurt. The many perceptions we have may change or become or become more 'rooted.'
Oh, this is too complicated for me right now - LOL, shooting from the hip, if you question it, then I don't think it is a good idea. If you are resolute the 'us' of the relationship will flourish, then by all means yes. (this is just a view based on my life experience & observation)
