So, it's horny and more honest, but I think the reason I can get so incredibly horny about nullges (locked or not) is that they're big, kinda goofy looking, and also extremely not a cock.
It gives a big, obviously lewd focus to a form that is clearly not male and doesn't really serve a purpose beyond just, being lewd.
The humiliation aspect of being a kink toy that can't actually fuck or be fucked by anything is also really good.
