If you are only talking about fetish and desire than the man sitting next to you is probably Christian Grey. While they may have a different kink, it very well could be equally potent. Of course most men do not have the money, power, and prestige to indulge in those fantasies like Christian Grey. They have to navigate acceptable social mores and generally it is unacceptable to suggest tying a woman up on the first date (even for a woman who fantasizes about Christian Grey). Heck, just saying a woman looks nice can be a minefield these days.
The real question then, to me, is if there are really women out their like Ana. Afterall, what is Grey without her submission? The truth of BDSM is that both players have power in the relationship and ultimately it works only with respect and trust. That is the part which separates reality from fantasy.
So my answer would be, yes, there are probably lots of men out there like him, but establishing such a relationship takes openness, communication, and trust, which requires a lot of work that a book never asks of you.
