He definitely uses sex as part of his arsenal of control techniques. Abbey mentions on her blog that he seduced both her and "Diamond" as different personas, and it was obviously as a power ploy. He also keeps trying to encourage teenagers to get married and have babies. Plus, in her journal, Diamond goes into how he kept badgering her to have sex (not with him specifically as far as I can tell, but just to have it), as if her never having had sex was this huge moral stain on her character and the only important thing about her.

He needs to be off the internet years ago.
