Trans woman checking in here, kudos to Phobos, John, HCL and Longpageboy for the good discourse.
I have seen men on Kinkyforums here & there, also less popular long hairstyles such as Afro textured hair, long tightly curled hair (think Keri Russell in the 90s/Marina Sirtis on StarTrek, Fran Drescher in the 90s, Jerri Manthey, etc.), locs and box braids. Men & trans people can & very often do have long hair, and indeed, there are some who do not look trans to most folks' eyes (especially with bottom surgery and hormonal treatment)- people like AryaLeen, Camellia Wu, some of the Thai & Indonesian ladyboys I've seen online, some of the Pornhub, LongHairThai and Xhamster shemales etc. Plus there are male long hair models out there, such as "Hairfreaky" on Youtube, Daniel Herberg of HairForce Kalendar, or Japanese actor Ange Hojo, who have better hair than some of the long-haired women (be they natal or trans) I've seen
I believe Vino runs this site, regardless I'd like to see him chime in, and from my knowledge of his tastes & from lurking on here for a decade before I decided to start posting, I think Kinky Forums is an equal opportunity zone for beautiful long hair on adults, regardless of sexuality/gender/race. What *I* don't like seeing on here is underage youth, hair cutting, spam with no relation to long human hair or our shared fetish, and degrading porn, and I think most of us could agree.
