All too many people never sit down and figure out what it is that they really want. Instead, they take cues from popular culture, i.e. the television and just go with the flow.
Women who decide they really want a home and family are belittled and scorned in popular culture as deadbeats. Men who want a home and family are ridiculed as being either timid and weak, or overbearing buffoons looking for a slave.
So marriage and family is portrayed as the domain of losers in popular culture.
As a result, sex becomes something you do to someone else, not with them, and that goes double for men. It isn't the center of marriage and making a family. It is a drug, and you have no more care for the other person than any other pill you might pop.
Happiness and contentment is not possible without maturity, and you cannot mature if you fail to make big decisions involving big commmitment.
