I don't know if I would agree with that last line at all. In fact, most older women are the ones just reaching their prime and have learned how to achieve a level of intense orgasms. I still have not had that yet, but can't wait til I do lol. I am much more open about sex now than when I was in my early 20s. I am more comfortable in my own skin, and that reflects in my interactions with others.
I have also seen the majority of women in their 40s and even 50s, blow away any 25 yr. old in body appearance. Working out is universal to all ages, and so is plastic surgery lol, so you don't need a young girl to get that. Take Julinka from the Gulf Coast for example....I have yet to see many women at ANY age hold a candle to her in body composition. She is flawless in that respect and is in her late forties.
Dallas is another prime example of what you claim only younger women can provide...."energy levels." She can take more pounding than anyone I have ever heard of in my life, and keep that pace up for EVERY client she sees. That has more to do with desire than energy btw.
