I don't want to tell you what you're feeling, but it sound a little bit like you'd like to be pushed but it scares you. If that's so, I really think you'll be OK. Don't worry about what's on your no-go list right now. You might find that some of those "icks" are somewhat interesting in another context, while others might just always be icky. As you've seen, you can fall into a dynamic with one person but you might fall into a different dynamic with another.

In terms of your current Dom, your limits are allowed to change over time. He might like it if you invite him to revisit some of them.
