Re: The bell end factor
"Consent" is what is obtained by EULAs or by having "we will record you" stamped on a sign in a disused lavatory guarded by an aging cougar with too much makeup.
"Explicit permission" is what most people would think of as "consent" which means "actually getting their permission in written or verbal form"
"Enthusiastic participation" is the new California barrier that men have to meet to ensure that the women they're sleeping with aren't being raped. It hasn't really been well defined yet.
The legal definition of "consent" shouldn't be enough for anything any more. "Explicit permission" is a far better standard.
