Now

Paul is introducing a new topic in his teaching.

the things about which you wrote me

The Corinthians had written a letter to Paul to ask for answers to certain questions.

for a man

in this usage, male spouse or husband

it is good

AT: "it is right and acceptable"

But because of temptations for many immoral acts

AT: "But because people experience temptation to commit sexual sin."

each man should have his own wife, and each woman should have her own husband

To clarify this for polygamous cultures, "each man should have one wife, and each woman should have one husband."
