But he's not a sex worker. He's purposely going around having with random guys because he's doesn't value himself. He's letting others do what they want with him. They just happen to give him money cause THEY think he's a sex worker. Except for 1 guy we have no clue it the guys who paid him respected him or not. Though seeing how he said he was looking for someone to treat him like Akira did we can guess they treated him decently.
He has no self worth which is why he is sleeping around, not the other way around.
Of course not everyone who sleeps around has no self worth but it is something that some people do.
I really hate the stereotype that being a sex worker means you have no self worth. Sex work is real work.
