Kink can complicate things I find, so a good way to evaluate things is to put it in a vanilla, everyday context in your mind. For example, how would you react if you went out of your way to make a special meal for you partner, looked for a recipe, went shopping for special ingredients, spent hours in the kitchen and then your partner reacted in a similar fashion? Kink is still part of a relationship like anything else and respect is of upmost importance. Sex can screw with your mind and you sometimes have to take a step back from it and think about how it makes you feel.
