Just like the answers to your question, it is a mix. There are a number of people who just play with the fantasy and there are a number of people who take it seriously. One thing I like to point out is the growing popularity of interracial cuckolding and the increasing number of white men locked in chastity. Regardless of how many of these people who now practice these are “into” bnwo play, the fact is they are all in some way making it a reality.
And there is no question about it those two things are rapidly growing in popularity.
Personally, I am a supporter and love seeing the increasing popularity of interracial cuckolding and I am especially thrilled to see so many white men embracing chastity.
