I don't know the answer to your question, I'm (only) 58 myself, and the older I get the more sexually adventurous I seem to become. I can't imagine not feeling this way. My 3rd wife, living in a different part of the country right now, is 34 and our kids are still at primary school. When we took the eldest to enroll in a nursery school, the lady in charge asked if I was the grandfather? I wasn't offended and my beautiful younger wife thought it was funny. It is true that when one gets older one becomes more aware of ones vulnerability, but feeling old is only going to come with ailments and depression I think. Perhaps if a person suffers from extreme vanity then depression will strike at an early age. A greater risk of offending people ,when referring to their age, will come when calling young people children, or at times treating them as such. Youngsters want to be grown ups from the moment they are aware of adulthood, and long before they consider the implications. Not sure my post is of much use to you; however, being quite happy to be considered a "dirty old man" I just hoped my response might raise my profile on the site and maybe some young chic,or guy, or preferably both might want to make use of my presumed experience to explore their own sexuality. Or just fancy a shag really.
