no
None of the above! MC consents to all sex, though ML is not exactly a green flag as he just sees MC as someone to have sex with but he doesn't abuse him in anyway.
so not both their first time?
No
For MC we aren't sure if it's his first time but he's an adult and aware of what he's doing. For ML, no it's not his first time having sex.
does this have rape? ex? third party? non con? whoring? SA? is it not both their first time?
just to be safe
