Nope, it doesn't ;-)
Maybe a bit much, especially if he has no experience or knowledge of BDSM at all. Maybe start a bit softer, like asking for a bit of rope or being slapped, because it makes you hot. If it works, get into more right-on discussions after that.Going the (rather blatant but very hawt) way Ozme suggests seems like a good idea.
All the best
But as was said, only you know the guy in question. However, I am afraid I agree that the only way is to breach the topic honestly, one way or another, but clearly.
