Poe is a romantic and he fell for Finn almost immediately. They start as friends and when they start getting physical Poe is careful to take things slow since Finn doesn't have any prior experience. Things are going great but Poe doesn't know how Finn would react to introducing kink into their sex life. Poe is a Dom and he's always specifically looked for subs since its a big part what he's always wanted in a relationship. He doesn't know how or even if he should bring it up to Finn. Not only is Finn practically a virgin, but he's leaving a life where every aspect of his life was under someone else's control. What Poe's cravings may be the last thing Finn wants.

In the end Poe finally comes clean or Finn figures it out. They have a whole conversation about agency and trusting Finn to make his own decisions. Turns out Finn is super into the idea of subbing for Poe. And they all live kinkily ever after.
