I need to fap harder

Ugh, no. Edging doesn't help you last longer, it just makes you want to burst more. The trick is to strengthen your PC muscles so you can hold back ejaculation even when you cross the "point of no return." So what you get is a mild orgasm and you'll be able to continue pumping away with renewed stamina.

That always ends with like 1 1/2 INTERCOURSE.. (not including foreplay etc etc)
Which is not as fun as it sounds.
Because it is an unstoppable erection- that eventually becomes annoying.
