I'm not sure i believe all that as most older women genereally aren't open to trying new things anyway. That's not what the turn on is for me anyway. In fact i quite like the thought of being able to teach an older woman a thing or two.
A perfect example for me...she's a pro dancer off the UK version of dancing with the stars....something about her i find so hot....Apart from the fact that she's nearing 40 and fitter than most 20 year olds.
