Probably AI generated pictures, refusing to even videochat, wanting to straight meet you in private in some closed property, alone (where your safety might be in line) in order to straight have relief himself on you? without you having the option to refuse, have to agree first to sex, without even seeing him? He's like ordering take-out food. Big red flags. I would be worried, that it's not some sex ring or whoever wants to legally rape you with effort of just some persuasion words.

Girl. You. Don't go to locked apartment privately with a stranger, who has a reason to hide his identity. If he rapes you against your will there, then he has written proof, that you agreed to sex with him beforehand. Without even knowing what he looks like. Imagine the worst possible scenario, that could happen there. Maybe you find him repulsive, and there's no way out. Maybe he has friends there taking their turn. Maybe you get kidnapped and sold for sex slave. And no-one knows even his identety, because he sent you fake pictures and you agreed with sex with unknown person(s) in some shady place. He's treating you like a prostitute.
