Matthew Poole and continuators on 1 Corinthians 7:4

4 The wife hath not power of her own body, but the husband: likewise also the husband hath not power over his own body, but the wife .

He gives the reason of it, because marriage takes away from each married person the power over his or her own body, and giveth it to their correlate. The Apostle seemeth here to answer a question propounded to him by some Members of this Church: Whether, though they were married, the husband and wife might not forbear each others bed, and make use of their society each with other meerly for helps in other things, such as getting an Estate, looking after the affairs of a Family, &c. which the Apostle doth by no means judge advisable.
