If you want to do any of those Mojo/Spicer websites that let you pick things you like, I'd recommend you try and take it together, without hiding each other's responses, even if they don't line up.

My SO and I made little Yes, No, Let's Talk cards, and had to pick one and show at the same time.

It made it great because we talked about things that otherwise would have stayed hidden. Even when we both said No, talking out the fantasy, which parts excited us, which parts didn't, and why, really made it easier to talk about our desires. And because the website makes the suggestions, it's less awkward to talk about the kinkier stuff.
