why can't men take no for an answer?

this question has been asked a million times

Women don't even know what they want! it's women who can't take no for an answer. Not in a sexual situation but in everyday life. 

the reason why men don't take no from women is that we know that women will give in sooner or later.

you need to send a strong message, be straight forward so there will be zero chance the guy can say that you are sending mixed messages.
