Wow, how interesting it would be to have all you dudes in a room demonstrating your techniques!
Gigantikok mentions smaking noises being arousing. How true, when my foreskin covers and uncovers the head it often 'pops' and stimulates me even more. The more senses involved the hotter and harder my dick becomes.
ThighSlapper and Zot57 use my method of changing hands to free up the right for the keyboard and mouse. I usually tighten my kegels a few times, while my cock is hands free during the change over, to watch it come closer to my abs.
Knowing how sensitive my dick head is, the two handed jacking seems extremely appealing. It's fun to think how far out from your crotch some of you guys put your fists while stroking the length of your hardons.
This has been a very informative thread, to say nothing of being fucking hot.
