than the girls actually do. Even girls who are promiscuous need to pretend they care, hence the need for 装B. Of course that's assuming the guy wants more than just a one night stand, otherwise neither will give a crap.
I guess comes down the the level of girls' hotness (hotness can be many things). A 8 or 9 will get me to jump through a lot more hoops, a 5 or 6? not so much.
