I have people who Have documented nerve damage and can’t feel anything. I still numb them up, simply because we can have knockdown effects like vagus nerve stimulation even if they can’t consciously feel it. There’s still a response and, it doesn’t cost me much of anything to numb up an area just like normal.
I may or may not have found that women hugged me longer and smelled my hair if I used something the smelled good. I also used conditioner with my long hair and had many women running their fingers through it.
It was nice. Short hair is so much easier, though.
