slake your lust

   (of a male) to copulate

   Usually extramaritally, from slake, to quench or satisfy. A man may also slake his (base) passion:

    ... let him slake his lust on one of his own serf-women. (Fraser, 1973)

    Having slaked what the lady novelists would call my base passion, I staggered up and collapsed on the bed. (Fraser, 1994)

   In obsolete Westmorland dialect, a sleek-trough was a prostitute, the cooling place into which a smith plunged his red-hot iron.
