Just to put it into perspective, I last about 10 minutes with slow thrusting and less than 3 or 4 with hard thrusting. That is with a condom. Two handed handjobs, less than a minute. I'm trying to train myself to let my mind wander during sex, and it does help sometimes, but is there a way, via masturbation, to help improve my performance? I've heard the stop and go technique, but that's how I masturbated all those years, and if I want to I could ejaculate in less than 20 seconds. Would artificial stimulation help? Like if my body got used to cumming with say.... some crazy contraption, would the real thing be less intense? Does beating up your penis before sex help? I mean like stretching or squeezing. Anyone have any ideas?
