Dear Crow,Oh Mate this is a vast simplification,growing old wreaks havoc on a Males sexual powers,at 40 it is said 40% have problems,at50=50%,at 60=60%,but at 90,20% still manage...but it is not all downside...As Bretto suggests,as you age you get more experienced,this is true particularly if you work out,eat well and keep your mind alert...Can I say as a young man I would be a bit rough,girls in general like a slow gentle lover,also my sheer enthusiasm caused premature ejaculation...now the decline in sensitivity together with learning a few techniques enables me to keep going for an hour no worries,Kegals have been a great help...At 64 I still manage sex most days,on a recent cruise with a lovely Chinese girl,we made out three times a day...I have always kept my pipes flushed as a matter of health...Use it or lose it...for someone still working the consequent drain on nutrients and energy would be a problem...I tried the Tao approach,trained and yes no problem,but my fear of Prostate problems,the curse of older chaps,made me go back to the natural way....So don't be too worried about aging,the pool of Women increases as does the age difference you may aspire too....My learning to dance was what opened fit sexual young Women up to me...Another observation is that Sexually active people don't seem to age as much as their less active contemporaries,now most people would conclude that this is not a surprise,that they were genetically superior to start with,others that the environmental stimuli encourages healthy life styles,but I believe that sex actually fools your body into thinking it is young...So Lads bang away for longevity....
