"Try to masturbate with your other hand. I think you are going to be very surprised about what you will discover. Many people will find it impossible to masturbate until ejaculation with their other hand. Most people do not realize it, but they cannot use their other hand very well at all. They might be able to turn a doorknob or hold some car keys, but trying to eat dinner with their off hand, or trying to masturbate with their off hand, will be impossible."
The guy's trolling, but it's pretty funny, as far as it goes.
Obviously, people watching him have gay sex in videos have transferred their pud-wacked-ness to him. That's why i don't do it anymore. Not gay sex mind you, just masterbation.
