@kwendy I doubt that someone has made any research on the topic "with what fantasies do you masturbate on gay content with the opposite sex", lol. In any case, it is obvious that we were talking only about readers of this content.
This has bothered me for a while but I think a better translation of the whole XYZ thing - kusai no yada kara zecchou suru - would be: Since I don't want (it) to smell bad, I'll climax.
