This is something I've been thinking for a while under a few different scenario.
It started only about sex, and now I think it should be applied overall.
I'll be very brief, maybe going a bit deeper if there's any interest.
The last regular girl I had was super cool.
In the beginning.
Only to change a lot later on, both her and the relationship dynamics, as it was getting more and more serious.
The issue there was that she liked me too much -she said I was "almost perfect"- and was tip toeing around me, bending to most my every will and showing only the best trait of her behavior and holding back her true self.
As it was getting more serious, she became more and more "herself", tiptoeing less and less.
So to get to know your partner quickly, ideally, you want to be good, but not amazing either.
Be good, but not to the point she feels the need to appear better than she actually is, or it'll take you ages to get to know the "real" her in a relationship and, sometimes, it might be too late (marriage, children etc.).
