First of all, this is a long hair forum and i guess it is officially not restricted to female hair only. Women also can like men with long hair and yes, trans-people can have or / and enjoy long hair as well.
Like already noted, some of these trans-women look more female than some other not-trans models and if they feel female and look female, there is nothing wrong about it when you apreciate their silk.
You sound more like you afraid they might have bigger balls than you. First of all maybe for real on the biological side, but most of all when it comes to strenght and bravery, because they show themselves. You on the other hand miss the strenght or / and the brains to accept them.
