I think people should stop fusing the two elements together. There is the animal physical attraction inside all of us which instinctively gives us the want for sex.

Then there is the reproductive aspect of it. We have to do it if we want to keep the human race alive. Obviously, not everyone does it for this reason, but that is why we humans are not asexual and can't reproduce by ourselves.

Where people get confused is when relationships spring up. Do you need a relationship to have sex? Obviously not. Is sex better when you are doing it with someone with whom you are in a relationship with? Depends on who you ask. Sex obviously wasn't meant for just people in relationships. As far as the conflict with how women view sex and how men view sex, you have to find a partner who either feels the same way you do about the counteraction of sex and relationships or who respects your moral standards enough that the abundance or lack of sex in a relationship won't cause strife and disagreements.

Of course, this entire philosophy on men and women's views of sex is thrown out the window when considering gay or lesbian relationships.
