This will only work if you have a partner in bed with you. So I'm assuming since this question is asked in M&D that you have a partner.
Take a bowl of ice cubes and place them next to the bed. When your approaching climax, have you partner place an ice cube at the base of your testicles, the cold will cause the urethra to constrict stopping the urge, you can repeat this process as long as your partner wishes.
Good luck.

Slow down....take breaks when you get close and use your hands or tongue more....masturbate a couple hours before you anticipate having sex....think about things other than how good it feels until it is time to finish...don't alow too much stimulation to your "man parts" during foreplay....use condoms (some are thicker than others and some include an ingredient to slightly desensitize a man during sex). There are lots of ways to last longer and get better, though practice is usually the most effective. The more you do it, the better you will get.

See a doctor.

Count the number of pumps. Have a goal to increase that number every time you have sex.
