7. They want to see how sharp you are
A woman wants someone that is smart and confident. One of the proofs of such intelligence is being able to woo her into having se_x with you.
8. They do not want to be used
Most women know that if they outrightly tell you how much they love or want s_ex, men will take advantage of that and use and dump them.
9. They do not want to look cheap
Women pretend not to want se_x so they will not come across as cheap. While a man is allowed to be a horndog and chase women, women are not allowed to come across the same way.
