No, it doesn't matter, but Shidou sure as fuck doesn't mind because he likes it a little rough. Maybe he should consider letting Denji fuck his face, make Shidou choke on his dick. That could be fun. Oh, yeah, that could be lots of fun.

When Denji warns him he's going to blow, Shidou pulls off, so just the head's in his mouth, his hands coming back up to Denji's groin, one palming his balls, the other working his shaft as he keeps sucking on the tip.

He wants this kid's load. He wants it so bad his cock is throbbing in his underwear, leaving a wet mark where his pre is leaking out of him. He keeps jerking Denji's shaft, and a finger goes behind his balls to tease that sensitive patch of skin between balls and hole.
