i personally like the idea of openness... as in.. all the past of ur partner are discussed and revealed..

coz i wont feel ok and will really feel bad/mad, if i discover something about him which he never have shared to me yet. even if at that time im not yet a part of his life... it may hurt but will soon be accepted...and be get immune... so when time come that i'll get to know about him from other person..or in some circumstance ... i know how to react and know the whole thing already ..

the virtue of acceptance is developed in the relationship then..

though there are women too, choose not to know anything...
