Sex is better done as a result of some bond/connection, but it can be done without too. The bigger question you need to ask yourself is, do you get laid together because you really love each other, or is it because the woman, for example, want to make the man happy in their relationship, so he will pay for her more, or love her more, and so on, ?
You dont always have to give it so much thought like you might do, because sometimes couples get laid just because they enjoy sex, without a special reason to do so. But I have a feeling men care about sex alot more than women, although that might not be the case always in every relationship.
