One variation of this is called the “7 and 9” technique: keep yourself (and potentially your partner) stimulated without going over the edge of climax by alternating between seven fast strokes and nine slow strokes.

Look for a cream that absorbs into your skin to prevent numbing your partner as well.

Avoid foods that are high in saturated fats and cholesterol, as these can clog your arteries and reduce blood flow. Good blood flow is vital to having the best sexual experience. [4] X Research source

Masturbation is also a good way to train yourself to control your climax. Practice getting close to orgasm but stopping right before. Repeat several times before you finish. This will help you learn to notice when you are at the edge of climax, and control yourself when you get there. You don’t have to do this every time you masturbate, but occasionally challenging yourself to see how long you can last can be fun and helpful. Masturbating too often in the same way, however, can train your body to only respond to certain kinds of stimulation—which can be troublesome when you want to reach your climax during intercourse. Be sure to vary your routine: switching hands, using lube, trying sex toys, and exploring different kinds of mental and visual stimulation.

Avoid thinking about topics or images that stress you out or turn you off. These can cause you to lose your arousal during sex, instead of simply letting you extend it. Instead try to think about something more abstract, such as visualizing geometric shapes or recalling the lyrics to a favorite song. Don’t extend your stamina at the expense of being present with your partner. Long sex can be dull for both of you if you spend the whole time with your head in the clouds. Use this technique sparingly and instead focus on engaging and being active with your partner.
