When reading that passage, I didn't think of anything about chastity. It seemed to me that the Duke's son just wanted what he couldn't have. If he were married to her, the thrill of the chase and the thrill of doing something wrong, would dissipate.
He just strikes me as a whiny little boy who wants things based on no real reason besides passing fancies. He wants to sleep with Castiza but definitely does not want to marry her- he's not mature enough for that. Possibly he realizes this about himself, and that's why he makes it clear from the beginning that marriage is definitely something he is not looking for.

"Oh, come not near me, sir; I shall defile you.
I am that of your blood was taken from you
For your better health. Look no more upon't
But cast it to the ground regardlessly;
Let the common sewer take it from distinction.
Beneath the stars, upon yon meteor
Ever hung my fate, 'mongst things corruptible;
I ne'er could pluck it from him. My loathing
Was prophet to the rest, bu ne'er believed;
Mine honor fell with him, and now my life."
(The Changeling V.iii.158-67)
