Normally, I can go as long as I want but when I haven't busted a nut in a week I can be sure to cum pretty quickly. Here's a couple of things to try.
Start in missionary and go super slow with some teasing strokes. Don't go in all the way for a few minutes. Once you've gone all the way in, just keep it slow for a while. Then you should be able to hammer away.
Also...you can touch the tip of your tongue to the roof of your mouth. Focusing on that will keep your mind off how good that pussy is and help you last longer. I think desensitizing your dick serves no purpose, other than to impress a woman. What about your pleasure?
My wife sleeps naked and is always wet in the morning. When I pull those covers back and see two round peaches and that tiny waist I slide over and bust a nut in under a two minutes...and those are the best in my opinion. Lasting a half hour is overrated.
