Explanation:
She lingers my desires, (She's keeping me waiting)
Like a stepdame or a dowager (The term "stepdame" also means stepmother, and a "dowager" is a widow who holds a title or property from her late husband.)
Long withering out a young man's revenue. (Revenue is synonymous for earnings, or in this case, a young man's inheritance that is being held by a stepmother.)
