'Relations' in the Bible

Now in response to the matters you wrote about: “It is good for a man not to have relations with a woman.”

But because of immoralities, each man should have relations with his own wife and each woman with her own husband.

Do not deprive each other [of marital rights], except perhaps by mutual consent for a time, so that you may devote yourselves [unhindered] to prayer, but come together again so that Satan will not tempt you [to sin] because of your lack of self-control.

If Timothy pays you a visit, see that he is free from fear in his relations with you; for he is engaged in the Master's work just as I am.
