I generally agree with you, except the details of the event that provide a pretty valid reason he stuck around: you can’t immediately leave a boat if something goes wrong.

Having sex in the middle of Lake Michigan to avoid police means not being able to leave that area if something like a birth happens. Donald stuck around because leaving would require him crossing a lake by himself. Something I doubt he’s capable of, even in a boarding vehicle by himself if they had one.

And pedophilia is mostly about sexual attraction to power and influence, not youth. There are studies I’m not going to link, that you can readily find about this. So it’s a least possible pregnancy may not be attractive to Donald, but 13 > pregnant, so fair game for the ghouls to ghoul.
