Lock all the doors and windows,
Take the phone off the hook,
Get some lubricant,
Find some good porn online,
And just sit there and wank yourself silly! :smile:
Different guys require different amounts of stimulation. Your penis works, because you have nocturnal emissions (wet dreams). Becoming anxious over how long it takes you to orgasm will just make you more anxious and even LESS likely to cum while masturbating.
If you're on any medications talk to your doctor about your problem. If you're on an anti-depressant that could be the problem. They are notorious for orgasm problems.
