Could you just take half of a Viagra?
I guess I am a freak, I can orgasm at least 10 times without getting soft, but I've never been with another person. So, I'm not sure how well it will work.
I'm not sure if this will work with condoms, or if you need to change them after each time. But, what I would try is masturbating with a vibrator or something else that will provide more stimulation than normal. And train yourself to follow this pattern (normal stimulation, orgasm, 5 second pause, high stimulation, orgasm, 5 sec pause, high stimulation, orgasm, 5 sec...) The glans will get way to sensitive, so hopefully your frenulum area will be able to handle it. They are different types of orgasms though. Mentally, think about the sensations, not the goal of reaching orgasm.
I probably should try to find a girl to experiment with in real life.
