A lot of good advice already given, I think.

Look at it like this...you and him had sex for the first time a relatively mere 3 weeks ago. That's hardly much time...it, in all likelihood, is going to take a little time for him to be able to gauge and react on your reactions, so to speak. As Trippin' said, he probably doesn't want to make you feel as though sex has supplanted the emotional part of things as the main focus of the relationship.

lol As far as the kink goes, again, look at his perspective. The way I see it, it's going to take a bit of time before that truly surfaces. Bear in mind, 3 weeks ago, you hadn't had sex *period.* Likely, he's operating under the notion that since it IS so new, it'd probably be best to take things slowly...let you get comfortable, in a manner of speaking. Let the newness pass. Besides, from his perspective, it's a bit of a leap to go from first time to "So hey, I have this bottle of whip cream in the fridge..." in 3 small weeks. Ultimately, communication is key...don't be afraid to talk to him about things. If he doesn't know there's an issue, there's no way he can work to fix it, right?

Lastly, disregard the previous girls...they're the past, and should stay as such. He couldn't have known then that he would meet you when he did...it's an irrational expectation that he rebuff his previous girlfriends, if he did have emotional attachments (think "the one" mentality) to them, for a possible eventuality. Granted, as Useless Me pointed out, there is the notion of waiting, but with that off the table, he wasn't particularly out of line. It's like the opposite of a court case..guilty of being a committed relationship (and thus to all aspects of it provided both partners are willing and ready to engage in such a thing) until proven otherwise. So try and let it go...it's the past. You only do yourself and him a favor in letting it go.
