How do you express the need to experiment a sexual desire with your partner that you feel may make them feel uncomfortable?

My partner has one comment everytime I express a sexual desire which is ' Oh ok are you sure you wanna try this out? Wow!!! " The fact that I too like him are the experimenting kinds makes his readily and quirkily accept the desires I put across each time... Moral of the story: Desires are easily acceptable if your partner is as sexually charged as you!
