Men and women should be looking for good characteristics in a person, which demonstrates attractive qualities. That also, reflects their values.
Looks, preferences and hobbies are not fundamentally important. They are superficial to actually getting to know the person personally.
If we practice celebacy and abstinence, we would make better informed choices concerning who we want to be in a serious relationship with. Without irrationally going by impulse.
And if we seek God in the matter, we can find the right match.
