This is where actual experience comes into play - spanking virgins can only imagine how it would feel!
A lot of emphasis is in the force used, and the implement, 100 spanks with little force compared to 50 of greater force for example. Prolonged spanking with adequate warm up can protect the bottom from damage, whereas no warm up and severe strokes may bruise. Heavy wooden paddles are likely to bruise anyway, canes will welt if the stroke is hard enough, but the sting of lighter strokes really counts at the time, but merely leave small bruises. It is also relevant as to the pain threshold of the spankee, we all have different tolerance levels. I do sometimes worry about repetitive strain injury to the hand where high numbers of hand spanks are delivered, or multiple spankings carried out by the same person, one after the other. I sometimes think the spankees in our stories are wimps as they cry and squeal quite early on, then, there are those severe punishments where I cringe and wonder how they tolerate it at all.
We also differ greatly as to what we will believe is a "good" story, humiliation is a thing I struggle with, but many thrive on it. I admit that I now write outside my own comfort zone, prompted by comments received, but then some people don't seem to like it.
So, our "kink" can be quite scientific at times, but it will always remain a personal preference as to the degree of severity, our belief in the reality (on a fiction site?) and the amount of enjoyment we derive from reading it. However, lets all enjoy it in our own way!
