An HD with self control that is not in a relationship would look a lot like an LD. You gotta do what you gotta do to damp down the fires if you do not have an acceptable outlet. But, a sleeping tiger is still a tiger.
I gotta agree with 5, I think masturbation is a big line of demarcation. If you can't get horny enough and "dirty" enough to take care or yourself or explore yourself, you don't have a sex drive.
