So you are replying to a post criticizing people claiming intimate knowledge about what other groups of people like, with a video of a person doing exactly that. Good job!
I will try to make it more clear. When it comes to a subject as complex as sexuality, it would be prudent to only talk about yourself. Because playing the self appointed spokesperson of others' sexual preferences/kinks is both delusional and simple-minded.
Not even if it's a group you are a part of. Because guess what? People are different.
