According to Paul, it's not absolutley necessary to marry in this life, but according to LDS doctrine, if we have the chance, we are required to be sealed (married) in an LDS temple for time and all eternity, to a spouse of our choice.
it's not only Paul who has opinions on the matter:
look at Matthew 19:3-12. Jesus says here that there are some who will not marry- either because they do not find a partner / are socially unfit for marriage, or because they choose not to marry. Jesus doesn't condemn the choice to not marry, nor does He command believers to marry- He leaves the case neutral, while emphasizing the sacredness and seriousness of marriage between a man and his wife.
