Couple of tips...
1) Relax, its just p*say...if you find yourself getting too worked up start thinking about something non sexual like baseball or football or politics...
2) When u are getting close to shooting just pull out and stop for a few minutes. Kiss her, lock her, suck her titties, eat her out or finger her until you get calmed down. Usually if you do this a few times and don't shoot you will be desensitized for a while and can go for a long time without worrying about it
3) if u Jack off, try prolonging it by practicing getting close and then backing off. It will simulate #2
4) Adopt a mindset that your goal is to make a girl "tap out", that is tell you she can't take it anymore which is usually done by her smacking her hand on you repeatedly or verbalizing it. I let the girls know before we go at it they are not going to be able to tame the beast once I unleash it...many have tried but none have succeeded. Rarely do I find a girl who take what I am giving out for more than 30 minutes, although its a real turn on for me when they can...
5) Perhaps one of the most important points is to get in good shape both muscularity wise and cardiovascular wise. Your testosterone level will be high and you will be able to pound for as long as you want without getting tired. Never underestimate the power of testosterone in b@nging. The look on girls faces whenthey realize they are in for an hour long plus absolute pounding is priceless...almost like a deer in the headlights look
