This is my third contribution now and always look forward to reading and trying out different methods.
Here's one that is mind blowing, hold your cock whichever way suits you but this time long SLOW strokes from top to bottom no speeding up about 1 stroke every 1 or 2 seconds the slower the better but harder to keep the discipline with the speed of the stroke. Not allowed to go any faster and when your getting close you'll be tempted but hold on and keep that slow pace you started with it will be well worth it in the end. Use the edging technique as well but keep that slow deliberate stroke towards the end you will by itching to go faster but thats where the beauty of this technique is when your humping the air and want it faster.
Hope you all enjoy.
