I was thinking about this the other day. My limits have changed over time but they've gone the other direction. My pain tolerance has gotten lower, my kinks have become more vanilla, and my limits have become stricter.

What has never changed is that i love to submit. Sessions are now tamer than they used to be. More mental domination, service, chastity etc. my sessions and thoughts tend to just focus on how i can make my dommes life better. Its actually a bit boring compared to what i used to do. I am sort of obssesed with how i can make submission feel real inside the boundaries of a pro domme relationship. In my bdsm relationships there is a lot less BDM but a lot of S and it does feel like true submission which i really enjoy.
