Not so keen myself. In my experience the young men l have been with see sex as some kind of endurance race. Humping like a dog, pounding away for ages. I tend to prefer married men no younger than about 30. They tend to make it mote enjoyable for me, they have been trained by their wives to pay attention to the all important bits. If I don’t get a couple of O out of it, they don’t get invited back.
