For me it's when the uke is confused/hate/reluctant to be on the bottom. Because usually when the uke is like that, the seme will push the uke until he's willing to submit -_- The highschooler side couple in Honto Yajuu is a good example of that I very much prefer a gay bottom uke that's not afraid to bottom and an understanding seme please :)
Full on full force rape type things... Like if uke/ seme are clearly against it. I’m fine with it if both parties consent. But if it’s forced that’s a no for me. reply
