I'm part of a lot of smaller women-centered communities on reddit - my favorite subreddits were r/MoneyDiariesACTIVE, r/FIREyFemmes, r/girlsgonewired r/adhdwomen, r/AmateurRoomPorn, r/AskWomenOver30, etc. Not all of these are explicitly for women only but they all have a majority female user base. I don't think there are equivalents in a forum-type format; I'd probably have to go to TikTok or something, but I don't care for that format so I'll probably just lose those communities for the most part.
