Dear Friend, please read the entire context of the below posted verse from Corinthians. Paul the Apostle gives insight how this is. This is not a condemnation verse, it is a directional verse. The world at large is largely hell-bound because they throw aside God's wisdom.

But if they cannot contain, let them marry: for it is better to marry than to burn.
1 Corinthians 7:9 KJV)

"Cannot contain" having physical desires that demand relief. Thus the instruction is to marry. It is God's method of placing stability and holiness in the relationship.

The epistle to the Hebrews is starkly clear:

Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge. Hebrews 13:4 KJV)

Amplified Bible: Let marriage be held in honor (esteemed worthy, precious, of great price, and especially dear) in all things. And thus let the marriage bed be undefiled (kept undishonored); for God will judge and punish the unchaste [all guilty of sexual vice] and adulterous.  Hebrews 13:4 AMP)
