Answer 1

KEGELS (Excercising The PC Muscle)
http://www.jackinworld.com/expert/10selfcont.html#kegelmen

There are exercises called Kegels for men that increase orgasm intensity. Kegels for men increase sexual feeling by strengthening the pelvic muscles. To get in touch with your pelvic muscles, pretend you're in danger of urinating or having a bowel movement but that you have to wait until you're near a toilet. The muscles you squeeze to hold it in are your pelvic muscles. To strengthen these muscles, start by holding and releasing them 15 times, twice a day. Don't hold the contraction — just squeeze and let go. You can do this unobserved almost anywhere — while driving a car, reading the paper, watching TV, during a meeting ... wherever. Gradually increase the number of squeezes until you're up to 75, twice a day. When you reach 75 at a sitting, instead of immediately releasing the contraction, hold it for a count of three, and then relax and repeat. Work up slowly to about 50 of these longer Kegels. Continue doing the exercises for six weeks, alternating between the shorter and the longer Kegels. The results should be noticeable in your orgasms after a month or more. Once you have the technique down, you can squeeze your pelvic muscles when you're having an erotic fantasy, when you're being sexually stimulated, or when you're having intercourse. Feel free to experiment and see what methods increase your orgasmic intensity the most.
