I do have some hard limits (age play, scat, etc) but I'm up for a lot of new things, as long as it sounds good at the time.
If I get a visceral "NO" reaction to something, I investigate WHY I feel that way, (instead of just never thinking about it again or ever trying it) and then proceed from there. My first encounter with a sex toy was a visceral "NO." (Although something very exciting about it, anyway.) But I investigated why I felt that way, and realized it was external programming that had given me the reaction, and worked past it, and found we really enjoyed it anyway, perhaps in spite of the external programming.
