so if demisexual is the one involving a connection. what of the one not involving ie soliciting a prostitute

hypersexual

No like, most people can find attractive people sexually attractive without there being much of a connection. Well, maybe it's a dude thing, I dunno. It's another thing to actually actively pursue such an attraction though.
If you're seeing a prostitute, that sound like you're just trying to get off without masturbation. I dunno.
