to me 7 minutes would be great. Do you tend to last longer or shorter depending on what your doing? Like for oral is it quicker than say a hand job or penetration?

yeah oral is definatly quicker.... depending on my mood/how long it's been it can be a lot quicker than that too lol

Quick hint, masturbate before you do anything with your partner it'll help you last longer.

I heard the more you masterbate, the weaker (as far as holding it in) you become. I'd been jacking off quickly (1-2min) for some time before i realized i had no stamina. To build it up i noticed what muscle it was that made me cum, and trying to control it. The more and more i worked on it, the stronger the muscle became. I suggest relaxing that muscle and learn not to tighten it up, cuz its the tightening then sudden release that causes orgasm. Just Follow Frankie's advice.
