I only know of a similar story: he didn't get a boner but was horny all the time and said that he "ejaculated looking at a cat's ass"...

The abstinence phase was in chapter 2
ohh my god that was it. thanx i must have gotten the quote wrong. good on you that you got a good reference from my terrible explanation.
Help looking for a manga i read a long time ago. they were a couple in high school who used to switch seme and uke. all i remember is that they had an abstenance agreement and one of them kept getting a bonner randomly and the other partner said "you could get a bonner looking at a chicken". i thought it was funny and just happen to remember. if anyone could help it would be great
