It is intelligent but also a bit naive, he did it in order to keep Riegrow away from Taeui since they made a deal, but it's definitely not decent. He considers Taeui a possession like Riegrow does. He doesn't want anyone to have him but he's alright with himself if he sells his body, sleeps around e.t.c. Obsession is entirely selfish, so the same rules don't apply to the obsessed.
that I saw him having an intercourse with Riegrow. I mean, Xinlu gets fiercely jealous about the idea of Taeui being together with Riegrow, but then there he goes offering his hole to Riegrow. How can that be intelligent or decent?
