When an orgasm begins, I keep on stroking, because it feels sooooo good. And, sometimes if I keep on stroking I can have another orgasm.

I've also found that's it's best to stroke and squeeze my cock as it's going soft to get all the remaining cum out. Otherwise, I tend to leak drops of cum into my underwear which can be uncomfortable, when it dries.

Incidentally, there's nothing worse than to be getting a handjob, and the person doing the stroking stops, when I start to cum. Damn!!!
