Hi guys, I'm looking for this yaoi manga that I've read a long time ago. The story goes like this, the seme has sex with the uke multiple times a day because the uke is very active when it comes to sex until the seme passes out(?) one day because of this. The uke was avoiding having sex with the seme and instead got sex toys from his doctor friend to relieve himself. The seme found out about the doctor and misunderstood that the uke was cheating and after clarification they reconciled.

I'm pretty sure it's the second oneshot, Dying Happy, from Recipe by Yuki Shimizu. 🙂
