Start off in the morning and stroke your penis until you feel yourself approach the edge of a climax. Stop and get ready for work or do something else. Continue doing this through out your day - masturbate until you approach the edge every one to two hours and then stop, tuck it in, and zip it up for later.
Drink a lot of water and/or fruit juice, this will keep your blood volume from dropping down (important for strong erections).
At the end of your day take one to two hours to pleasure yourself.
Start as you did earlier but just as you reach the point of climaxing stop and do something else until the sexual feelings die down.
You can listen to some music (headphones recommended) and concentrate at it instead.
Can also try taking your hand off your penis and tense your crotch muscles as you would to force out the last drops while urinating (your crotch muscles should be tensed when you first start to ejaculate).
After the urge subsided, Immediately start masturbating again.
Keep this up until you finally achieve a very intense and powerful orgasm.
Take some practice, yet with proper timing and pressure you should be able to orgasm and ejaculate two to three times before you obtain a full orgasm and your penis softens. Use light pressure toward the head of the penis as your orgasm approaches to help out. This works well both standing and squatting on your haunches.
