It is all about being conscious and aware of the effect that one’s efforts are having on the partner, and being willing to explore the avenues that can lead to those wonderful orgasms. One of the best compliments I have ever received came from a former lover who said that she loved being with me because “…you know how to touch a woman.”
My last girlfriend could achieve orgasm in many ways, but the culminating act involved digital stimulation of her g-spot at the same time that she crossed her legs tightly. It took some work to get to the right spot where my thumb could provide that stimulation. My hand took a beating, but it was a surefire manual technique for her.
