You can further elaborate on things or include links to other interests listed on your profile. This makes it a little easier to cover more ground in some aspects. These lists have the same issue as Human Sex Map in that many terms, especially those referring to people who are gender non-conforming, are offensive. As I said, it's a common issue.
The most obvious drawback here is that more than just your partner(s) can see your fetish lists. If this is something you're not interested in, then Fetlife isn't the place for you.
Mojo Upgrade
Mojo Upgrade is an app, and it's perfect for people who are worried about what their partner might think of them if they're into something that their partner really isn't into at all. This is a common phobia, and regularly keeps people from discussing things they're interested in with their partner.
The way it works is that you sign up to do it on the same or two different computers. You decide what your nickname will be, pick your gender (which is, unfortunately binary, and a lot of the activities heavily rely on you and your partner's genders), age, and whether or not you want "advanced" items added or only advanced options. Advanced options are more extreme kink and BDSM scenarios and actions. Then you each, successively, get to choose whether or not you're interested in something by clicking "no," "we already do that," "if my partner is interested," and "yes." When the results are finished, your partner will only see the things you answered anything except no to that matches their answers. So, if you picked "if my partner is interested" and they picked "yes," then you both would see the results.
There are definitely some drawbacks to this one, but the ability to leave things your partner isn't interested in private will definitely make it an ideal conversation starter for many people.
Go to an Adult Store
Piggybacking off of the assertion that talking about things in a safe but public space will help you concentrate on the task at hand, going to an adult store with a really good selection of adult items will enable you and your partner to look at things in person and discuss whether or not it's something you're interested in. Depending on the place, you might even get to try on some outfits to show your partner. This is a more tangible option than writing out lists, but can only cover what is available in the store. Perhaps going ahead of time and scoping the place out will help. The best stores are focused on sex education and body safe products. You can find a thorough list of these shops on the Superhero Sex Shop Tour.
What are some ways you've opened up the conversation about ways you're interested in "spicing up" your sex life?
