New International Version - UK
17 Let them be yours alone,
never to be shared with strangers.
18 May your fountain be blessed,
and may you rejoice in the wife of your youth.
19 A loving doe, a graceful deer –
may her breasts satisfy you always,
may you ever be intoxicated with her love.
20 Why, my son, be intoxicated with another man’s wife?
Why embrace the bosom of a wayward woman?
