I think it was more that he felt he retained some control. If a certain sexual act reminds him of a past trauma, then he was able to avoid putting himself back in that situation again. At the end of the day Sangwoo was an abused child too, and we don't know the extent of the abuse, only how his behaviour is as an adult and the coping mechanisms he presents.
Im in confusion..what does Sangwoo mean that “he won” so is he gonna kill Yoonbum now..i hope not..and what list was he talking about because they didnt show a list last time or in this chapter..(〜 ̄△ ̄)〜
