I see it as a kind of a Catch 22.
As singles, we struggle with the desire for sex, but no outlet. However, many of us cling to the hope of a POSSIBLE solution someday, no matter how dim it might seem.
However, even if we get married, we might have an outlet--for a while--but what if that changes and then there is NO outlet anymore, and NO hope, not even the dim possibility, of ever having another one? (Except for the very morbid, who might wish their spouse would pass away so that they can look for another.)
Either way, most of us eventually have to face the unpleasant task of trying to ignore or shelve our desires, whether sooner or later, and whether married or not.
