I was thinking this only earlier - on my way back from a punt where I had popped much sooner than I'd have liked!
With some girls, I'm at it for ages - multiple positions, etc. And then sometimes it's literally a few thrusts and I'm done
Today was one of those days...
As someone else said, a couple pints in me and I last longer - however I drive to all my punts, so that's not an option. I do have a pre-wank, and don't get any problems getting hard again as it's usually an hour or so later I arrive at the WG.
Getting hard and keeping hard isn't the issue. It's time from entering to cumming that's the problem.
My trouble is I can't take my mind off the fact I'm pumping away at a, usually, gorgeous little 20-something, so the thinking of something else doesn't really work either.
It's annoying I can make a wank last for ages, but a fuck nowhere near as long.
