jacki: No 2 ppl are the same so it will depends on our lifestyle i guess.
Then I would say the question of whether or not to change would also depend on many things, no?
There are ways to remain individual within a relationship, in fact I would go as far as to say that ideally (although not many things work out ideally) the purpose of a relationship is to enhance both and not diminish either in any way.
Thus if it is a minor aspect, it can be sacrificed for the good of the relationship, whether one or both party/s chooses to or not remains a choice for the individual. A major aspect is harder to give up and is not necessarily the right choice. This is true for both parties but is most especially pertinent to women as it is taken for granted that we are obligated to.
