Previous to my current relationship, I was always more of a dom, but now I identify as a switch because I'm definitely a sub with this individual.

We have both noticed that I keep needing to up the pain and that I want more and more because the old stuff just isn't enough for me anymore. We are worried that I'll top off and will just get bored and nothing will turn me on enough!

I've never experienced this before since I've never been a sub before this relationship. Has this happened to other subs? What do you do to solve this to make sure you don't get to a point that your dom isn't comfortable inflicting pain on you, or that you can't do much more without actually getting hurt?
