ACCORDING TO the "rainbow city" novel chapter 6 on booktoki, (spoilers)
"“Do you still not understand my obsessive trait?”
As Kwak Soohwan pulled up Seokhwa’s shirt, he slowly kissed his way up from the navel, matching his lips with the upward motion.
Nibbling, he bit the soft flesh above the navel and sucked it up. Red marks where he had bitten and passed on various parts of the neck and upper body repeatedly appeared and subsided.
“Biting, huh?”
With a short laugh, Kwak Soohwan completely removed Seokhwa’s shirt, putting his hands behind and embracing him."
(Therefore, I can recommend you "rainbow city" manhwa because the seme likes to bite, teehee. also SA on chap 3, best to skip)

I dunno about biting, but this one features teeth a lot

I’ve got a kink for biting and teeth in general. Strong men with sharp teeth
