I feel like Jin used to be top but the guy on the phone was the one who made Jin a bottom. When he gets too agitated he would have sex to relieve himself but the guy on the phone probably showed Jin “another way” to make him feel better, which is getting fucked in the ass. And now they have bad blood so Jin resumes to his previous self where he does the fucking, but he can’t be satisfied anymore because it’s not enough if he doesn’t get the D in his ass.
