When you feel yourself getting close, reach down and give your balls a gentle but firm downward tug. Just hard enough to be uncomfortable, but not enough to really hurt.

Also, I was once with a girl that gave terrrible head. So if I thought I was getting close, I'd tell her to stop and go down on me. it still felt good, but wasn't nearly enough to push me over the edge and it gave me the break I needed to calm down.

Lemonade outta lemons, I guess.
