I can see where the ladies may be more intrigued with the younger guys. Let's face it, they wouldn't give us older guys a second look in a coffee shop.
But in all my years doing this, I have had many ladies tell me they enjoy older as much or more as younger. Many ladies (like us) say eye Candy is nice, but bottom line is money. If both are there than bonus.
I have only met maybe 4 or 5 ladies who actually admitted they were turned on by older men.
Some ladies are impressed if you are somewhat fit and have a good attitude as well. Once they get to know you and see how you perform yourselves (as in having the ability to perform) and how you treat them I find they are more open to explore.
Many times I have heard older members comment on how the ladies like the way the older guys touch them or please them and look forward to seeing them as a result. Perhaps we are more gentle, or patient, less aggressive, whatever. They have also told me older are more romantic (little gifts , flowers etc) when we come to visit.
There are so many reasons WHY some members get more YMMV than others. Bottom line, money will help that situation. Be young and hot and cheap and the ladies YMMV will drop quickly. Let's face it they are here to make money not fall in love with every pair of pants that comes by.
