Every woman is different...usually I connect on some level with my partners, I love the diversity....it kind of depends where the energy connects. Details, hmmm, not usually physical unless its that she makes an effort to take care of her mind and body.
The Get To Know You Chat is the key to finding that detail. Good sex is in the mind.
Recently a new lady and I sat down, she said, "Are you mad at your wife or a hobbyist?" I said, "Hobbyist". She said, "We'll be a good fit. Let's go to the bedroom." -CLICK- She was right.
Last year, another lady and I sat on the sofa for a get to know you chat, realized neither had much to say, and began an amazing kiss. Something magical happened at that point. Either she is the world's greatest actress, or we connected. Matters not to me as the experience was intense. I am at a loss to describe the beauty of my time with her. Mutual caresses and touches alone are the stuff of fond memories.
Physical? Yes. When I actually met a lady, now retired, I saw the image of Botticelli's The Birth of Venus as I walked into her home. I was done for. It was just the way she was standing there in the hall, the morning light behind her blonde hair, the enigmatic smile, the position of her hands, her classic beauty...it's in the mind.
Sometimes you actually feel that electric connection when you touch - I did not include this in a review because it sounds sappy but with a submissive lady I actually orgasmed from the energy alone.
How about confidence - she doesn't color her hair - sending the "I'm hot, I know it, and this grey hair says I'm experienced" message!
How about the mystique of shared danger? Both she & I walking into an unknown situation, not on our home ground, both nervous, both relieved to realize we are safe, and the realization leads to honest play.
Probably not what the OP was thinking of but for me it is in her yummy mind.
