THERE's tons. do a search on Gintama both here and on myreadingmanga.
Harada has some gin/hiji that are really cute and really good. The two to stay away from are "Kabe" and the one about stockholm syndrome something like "menaicusari - " you'll see it. My fave is the one that has "Hamerari" or something like that in the title.

Check out this link https://myreadingmanga.info/pairing/gintoki-sakata-x-toushirou-hijikata/
Gintoki is top, Hijikata is bottom. You can just look through the tag, there's a ton of Djs. I'd advise not reading Harada if you're afraid of seeing Gintoki in a very cruel and sadistic way. Some of Harada's stories about the pairing are cute, but most are just cruel.
Is there any Gintama DJ where Gintoki is the seme? I cannot accept him being the uke. No. Just no. He's my fave character and imagining him moaning and writhing beneath someone is death to me. But being a fujoshi, I want a dj where he is the seme. Please give me a list if there is any. Thanks.
