Nice try.
Merely adding you own words in parenthesis does not make it so.
Where is it forbidden?
I mean, where is it forbidden/condemned/not allowed/ a bad idea/etc. without your adding to the scripture?
The words I added where only included to help you understand the verse.
A man is indeed one man. It could be any man, but the text is written in the singular form of man. It is one man.
The word wife, as you already know, is written in the singular form. It is referring to one wife.
Matthew 5:28 - But I say unto you, That whosoever
looketh on a woman to lust after her hath committed
adultery with her already in his heart.
Hebrews 13:4 - Marriage [is] honourable in all, and the bed undefiled: but whoremongers and
adulterers God will judge.
Exodus 20:14 -
Thou shalt not commit adultery.
1 Corinthians 6:9-10 - Know ye not that
the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters,
nor adulterers, nor effeminate, nor abusers of themselves with mankind
This all sounds very condemning to me for the adulterer.
