Differing thoughts...
In my mind, a hard limit is a hard limit, meaning that if someone really says absolutely, categorically "don't do this thing," then that should be it. I dislike hard limits personally, though. I prefer to have someone explain to me what the issue is and then put it in my hands to deal with however seems best to me, on a case by case basis.
See, I reckon I'd have the same intellectual curiosity if they had a hard limit I totally didn't understand, though mostly for the reason that if there's a tie to major psychological trauma, or nerve dysfunction or whathaveyou, insight into the matter would possibly give better guidance for how you want to conduct a session.
For instance, I have a friend with nerve damage in her legs that makes tickling around her knees
totally not okay. Nerve damage is completely non-negotiable. I didn't know about the nerve damage at first, but after she told me, not only do I
not tickle there, but I'm especially mindful of anything in the proximity that might stimulate that area and pose a problem for my 'lee during the session, and so, when possible, adjust position in relation to other objects accordingly.
If someone were to put in
my hands the decision to cross a boundary or not... ...well, then it doesn't seem like a true "hard limit" to begin with really, but rather a temporary trust issue with whoever you're having top you that you'd appreciate having discussed before going forward, so you can be comfortable. And it's okay to have those sorts of reservations, too.
Before a session, I always at least cover a basic spectrum of boundaries with a playmate to make sure they're cool with most anything that may come up. If there's a grey area, I inquire.
If I perceive a matter as a true "hard limit", discussion about it would be for informational purposes for the benefit of both parties, and not to talk them out of it nor convince them to hand that decision to me if they weren't initially so inclined.
Maybe hard limits are something you can negotiate when you're a person of a certain experience level, or rank or something and it doesn't really matter, but
hard limits as I understand them tend only to be moved willingly with folks with whom you afford an
extraordinary level of trust
acquired over time... If you have a hard limit, and I don't know well before our session what the limit is and why you have it; if I haven't discussed the matter at length with you, and if we haven't played before, I see no reason you should be handing the choice to cross that line over to me.
Now, circumstances and dispositions differ, and "different strokes for different folks" and all, but that's the way I see it. And understand, if you allow me to cross some weak "boundary" during a first session or somesuch (and this
can often happen with a number of soft boundaries when you gain a sense of increased trust and bonding with an intuitive and caring top before or even during the course of a session), you can call it whatever you like, but I'm not calling it a "hard limit" by any stretch of the imagination.
Hard limits are to respected, period. Anyone willingly violating the Lee's trust is in for some rough times, physically and socially. They're called Hard Limits for a reason.
This better reflects my beliefs, practices, and sense of appropriate repercussion.
