I've seen this shit before.
She's a fucking dyke and doesn't want to accept it. Transmasc/FtM are often REALLY into anal because that's what REAL MEN DO (because MEN HAVE PENISES and the ASS is the ultimate hole or something), and it helps them avoid the idea of "front holes," "pussy holes," etc.
As for the brown girls, looks like P.A.P. is a "brown girl" who broke her heart, that's what I'm gleaning from the journal anyway. God help P.A.P. if the internet ever figures out who she is. P.A.P. may not have even known she existed; this bitch is crazy.
I can see why they didn't want to release this uncensored; other people are mentioned. Who knows what's real, what's imagined? I've never been this down bad, wasn't this person in their mid-20s? Fuck.
