Which gender can boast having the real sexual dynamos? And which can have almost unlimited orgasms, with long build-up, as well as cool-down phases? And for whom do orgasms actually "energize" rather than deplete? In short, who are the real sexual animals among homosapiens? Correct...women. In a lifetime they can easily have five times as many orgasms as you (except for V-Bob) and many do. The joke about 30-somthin' y.o. women hooking up with 20-somethin' y.o. guys is no accident. But what if you're 40-somethin' or 50-somethin' and want to keep up with that (or those) dynamos? What if you want to perform on the order of what women can do, with a similar capability?
You can, but there's a price. Your seed.
There are two books I recommend. The Tao of Love and Sex,

In a nutshell, these Chinese dudes figured out (between 900 and 1200 AD) that if they were going to be able to satisfy their 5 or 6 concubines on any given night (which was required to keep peace in the family), they had to develop a methodology or philosophy. At its core was the requirement that as a man ages he limit, not sex, but ejaculation. There are drawings in these books of couples having sex, but although graphic, they're not pornographic.
It's an interesting philosophy too involved to go into here, but it's all about health, longevity and harmony between the sexes. It's a very wholistic view of love and sex.
I started dabbling in it a dozen years ago and it's been great. It takes the focus off the "goal" of sex and makes you enjoy the process in a new way. It's also energizing to delay orgasm to another session or another day. And when your partner sees the benefits, she'll love it.
It can be more difficult when mongering than during "regular" life, but I still practice it. I can see more girls and have much more energy. I also "target" special friends for the prize.
