I went through a misguided delusional period of trying to get something for my favorite nb pb and it's actually very awkward trying to reply to posts in psls because of the sheer number of people who put het or slash in their posts and not knowing whether they would consider your pb male or female enough for their request, whether they were basing their priorities on genitals for smut, or whether they were just a bigot who only wanted cis people.
