This is not a math problem... in fact, as far as I'm concerned, its not a problem at all. I just thought I'd solicit male and female opinions about age. I'm 50, so just about every provider will be younger than me (although I wish I had visited a MILF when I was college-aged). I've had good times with every age (even above 33... it's just a number I picked).
Certainly, age is no guarantee of fitness, or beauty, or enthusiasm, although my sense is that a few more years generally means knowledge of a few more "tricks" (like squeezing just before my O).
Any thoughts?
