>but there's basically no good anonymous one
There is a good female centric imageboard, that I lurk on, since they ban anyone that they suspect is a man or "moid" as they call us, especially trannies. Their most popular boards are /b/ and /feels/, so you can guess the type of subjects they discuss. Now you might say it's just female /r9k/ however 3 years ago, I'd say half of them were in a relationship, as there were a lot of "relationship feels" or "here is what my bf does to me" however most of those relationships were toxic and harmful. At some point, because some terf subreddits got banned, those women came into the imageboard, and now their population became anti-trans femcels, with anti-moid threads and a racoon-thread(threads about women, imagining men becoming weak, samll and dumb, like a racoon, that a woman could carry in her purse like a cute pet). I enjoy their terf threads and honestly, by reading all those posts, it convinced me on why watching porn while in a relationship is overall harmful.
I am sure, someone will ask for a source, but I will not provide it, as I respect their "secret club" and "no men allowed" mentality, honestly I even reported both men posting there, as well as women responding and giving attention, hope they both got banned, since they ruin the experience.
