That’s what got an unnerving number of them started. That and Role Playing of the same for fanfics. They used to do that, then sometime in 2014 (when I first noticed it in fandom spaces) it became evil for women to write their smutty yaoi fanfics because it fetishized gay men. Which proved they had never decended into male written gay porno, because it has as much in common with yaoi fanfic as penthouse letters do to bodice ripping romances. Both might describe sex, but they are both WILDLY different in how they do so.
