I have a thing about hard limits.
They turn me on.
Let me explain.
I think I've mentioned before that my absolute biggest hard limit is needles. I have a phobia of hypodermic needles and syringes, especially ones designed for blood tests. My phobia does not spill over into all sharp things; in fact, I have something of a fascination with knives. But how I react to sharp, pointy things really depends on what it is and what it's used for.
I also have limits with my nipples. They are acutely sensitive, and can't take a lot of abuse. Threaten me with nipple torture, and I will cry.
Here's where things get funny: my most exciting fantasies, the ones that shoot me into instant arousal and have me itching to come, are ones that involve getting pins stuck through my nipples. Obviously, I would NEVER want this done to me; this is fantasy alone, visions in my head that will never come to fruition. But the idea of it thrills me nonetheless.
The ultimate turn on: someone breaking my hardest limits.
Are other people like this? Do your deepest, hardest limits become your ultimate fantasies? Or is this just a sub/surrender thing?
