Friends with Benefits? Fake relationship?

Would you be considered their “friend with benefits” if your crush told you they liked you, but was “dating” someone, and they ask you for sex, so they can make your first time special, but neither of you asked the other out? Would that be considered a FWB, or a more intimate, shorthand relationship between two who haven’t asked either one out?

>by “dating” in this situation I mean one of them doesn’t like the other anymore, but the other is threatening suicide if they try to break up

If this makes sense ._.
