when I was younger I had the same problem, only my recovery rate was zero, I stayed hard, and kept fucking. when I hooked up with my now wife, we had sex so often, I just somehow learned to control it. I took great pleasure in pleasing my wife. almost as an observer, I loved watching her on top of me, with her great, large boobs, long brown hair cascading over her shoulders, breasts. her bouncing on my big cock, being deep and tight in her puss. she writhing with pleasure, and when she could stand no more I'd roll her over, pile drive her to a couple more orgasms.
