If it were ME and it was MY one year anniversary, I'd wanted to be treated like a princess like someone else mentioned. Its a romantic occasion, not something that particularily screams "kinky" ya know? The worst thing you can do is assume she'll like something new and different, and then realize that she definitely wasn't expecting something like that and get turned off. So I'd go for the tried and true : first take care of the actual ANNIVERSARY events, like dinner, a walk through the park, exchange gifts etc...then when you get to the hotel, take it one step further. Have roses in there, make a bubble bath with wine or champagne (always makes girls a lil randy hehe) and give her a full body rubdown. Relax her. Make her feel loved and appreciated. Nothing turns a girl on more in a relationship than being loved and taken care of. And when it comes to the sex, don't put any expectations or pressure on it, just let things happen the way that they will. If you expect something new out of her, and she's not cool with it, you could stand the chance of not getting any for a loooong time lol. Its a big anniversary, you don't wanna eff it up. Save the kinky shit for a day that doesn't hold such meaning where you have nothing to lose. Just my opinion!
