The most professional way of delving into this topic would be one where a person that has been sexually assaulted has "rape" fantasies. One might say why? How can one take the most traumatic experience and wrap this around pleasure.
I am a natural switch and am kink friendly. So for me, submission is about incorporating and and empowering women which I love to see. Conversely it also allows me to process and work through issues and situations for which I executed as a man in a traditional setting.
Am I that way now? No.
So this is about mastering the painful, awkward and traumatic.
For some folks that are high powered or highly intelligent, there are kinks and other aspects which incorporate "pain" such as spanking or to have loss of control.
There is a thin line between pain and pleasure, and the difference comes down to consent and respect. If one has neither, then it is trauma. If one has both, then it can be a salvation to a past trauma and pain.
I have stated elsewhere, while it makes me uncomfortable as a man to cause a woman pain or to involve the "rape" fantasy angle. I can do it and do it very well, because I have both the consent and respect angle handled.
The big thing is for the partner (submissive) to understand is that they have the ability to stop it and know I will 110%. That is super empowering.
For the hyper intelligent, there is the ability to go numb and dumb in a good way. There is nothing better then turning off the brain.
I hope that is a reasonable response. Be well and take care. If this is not appropriate let me know, and I will delete this comment.
