90% of your comment makes perfect sense but there is a 10% that can upset your theory
This 10% are the enjoyers, they enjoy beings controlled, then those intune for the sexual gratification. And then there is me.
Then clearly these adults, if identified, would not be candidates for what I am talking about.
And if 90% of adults who are not "enjoyers" find the pain unpleasant then that certainly is a decent amount, I think. And some of the "enjoyers" who are identified might enjoy it less if release was mandated before a spanking rather than intensified after a spanking as you suggest is the case with you and your wife.
I enjoy the satisfaction it gives me
wife and I always have to make love afterwards.
See above. LOL
I enjoy the loss of control and the cathartic feeling that emanate.
I dont love the pain but i love the focus it provides.
That last part says a lot to me. If you don't want the pain but find the experience still erotic, then perhaps being forced to ejaculate before a punishment spanking and then having the pain element intensified might actually serve the purpose of turning something more erotic for you into something much less erotic and more punitive. Just a thought.
In any event, I do think that your 90% designation is a good amount if their experience is unpleasant. And given my interpretation of the original question which I took to mean the spanking of children as a disciplinary practice in the home, I would suspect that that number might be quite a bit higher than 90% and that more like 99+% of spanked children would find a spanking to be most unpleasant.
Be well, too.
