You do know that Eden was just a small speck on the whole earth, right? The most probable scenario is, they were supposed to consummate their marriage, but they ate the forbidden fruit first, and they abandoned their God given mission to be like God themselves, that's the problem.
It matters because since you acknowledge God as the creator of marriage and sex, it is God himself who joins man and woman together into marriage; it was God who created Eve and brought her to Adam, not Adam realizing his aloneness and pursuing or demanding for a mate. Therefore it is unbiblical to desire for marriage while single, and acting on your own to chase girls accord without God bringing anybody to you, doing so undermines God's authority.
