Not all guys are the same. My ex-gf (whom I dated for a year) slept we me the first time, over a year before I ever took her out on a date. Then again, I guess that falls into the category that jubei mentioned, of guys falling in love with a girl after having repeated sexual encounters with the, without having earlier feelings for them. My point is, in response to the part about respect, there are some guys who do not think like that, and don't loose respect for a girl just because she sleeps with them very quickly.
