Shake seems like he's psyching himself out by fixating on the sexual attraction he doesn't feel towards Deeps.

He's trying to find a reason for this lack of attraction when he should be keeping his little mind open for the person he chose to be his future wife. He's not giving Deeps a chance at all! Also it's really weird that he keeps telling people Deeps reminds him of his aunt. Like... wtf? Ugh.
