While men and women have more choice, there is still the human nature of survival, wherein human minds are wired to survive and have a generation that will outgrow other generations. This attitude of choosing pairs wisely is done in order to further double the chances of survival of children and avoid mishaps and abnormalities.
I believe the answer is: Women's approach to sex is more relational and men's more recreational. In our ancestry, women most often sent their genes into the future by pairing wisely, and men by pairing widely.
These approach would most likely influenced by each gender's involvement in reproduction process. Women had to carries the fetus for almost a year. In that time, they would be in pain and their movement are extremely limited. Which is why paring wisely is a best way to obtain protections under that situation. Men on the other hand, only biologically involved during the sex.
