"Do you ever worry how far your masochism will go or take you? and how much more you may mentally desire compared to what your body/skin can tolerate. If today it is 1 needle, tomorrow will it be 10, 20, 100? Without the care from a good dominant to say, no enough, do you ever wander how far the rabbit hole will go?"
I used to worry about it a lot in the beginning when i realised and accepted my masochism, perhaps because it was all so new and i was discovering all these things that excited me, turned me on, that yes it would worry me about how far i would go.
I still do at times now, but those moments are fleeting, i wander perhaps this is a common train of thought for most masochists?
Mentally there are certainly times i desire more that what my body/skin can take, an example of this is back a while ago when my Master was caning me.
Im very receptive to the cane (most of the time) and can take a severe caning, usually slip into subspace quite easily and when i do, its almost like i cross the pain barrier, it just no longer hurts, its more of a pleasant thuddy sensation.
This particular time i was floating in my own little world whilst the caning continued, then i realised the caning had stopped, i was annoyed, i was enjoying the sensations, i wanted more, i asked for more, but he refused which quite frankly pissed me off, i begged that i could take more, still he would not...and mentally i could have taken more...but
physically i could not, which i realised when he released me from the table and i looked in the mirror, my ass/thighs were a bloody mess, literally a bloody mess, much more caning and the risk of permanent damage would have been high.
So thinking about what you said about if today it is 1 needle, tomorrow will it be 10 etc (which btw, as i love needles, 1 would never be enough and nor would 10 lol) i do think elements of s/m can be addictive, or rather the sensations that come along with certain activities.
So if indeed these are sensations that one derives pleasure from, and enjoys the activity it stands to reason that one will seek more, or perhaps as it is in my case, i do tend to want to seek out new edges, to find a new high, and the s/m spectrum is so diverse i could keep going for a long, long time.
When or if it gets to a point that my Master, and myself to a certain extent, no longer finds enjoyment from engaging in such activities, then that is when it will stop.
Thankfully i consider my Master a good dominant, and he is an experienced sadist so i try not to worry about how far down the rabbit hole i will go, because i know i have him as my safety harness and he will say "no, enough", but yes i think if i was in different hands, that of a dominant that really didnt give a care about my mental or physical well being then i could potentially be dropped down the rabbit hole a lot further than i could emotionally/physically handle.
Thanks for the question, i hope my reply answered it sufficiently.
