Hey, I know lots about male sexuality stuff because I get LOTS of educational spam about it in my e-mail!
I wasn't talking about masturbating, I was talking about "having sex" -- and that the "spent" feeling is more likely due to the amount the physical engagement required to carry out that act with another person. Factor in all of the expenditures, physiological, physical-muscular, emotional/mental, and they do add up. As for masturbation, you may not feel "spent," but you probably can't do it again for a while, due to the refractory period -- which is also physiological and not anything to do with losing energy from the teaspoonful of ejaculate itself.
However, life is all about reproduction/genetic replication, and while humans are particularly long-lived and capable of having numerous sexual engagements without losing their "life force," there are many organisms that are "programmed" by their evolutionary traits to focus all of their energy in rapid growth and development to the point of reproductive capability, then to reproduce once and die. Think of salmon spending years at sea putting on enough body mass to make the arduous journey back to their freshwater birthplace to spawn and die. Or desert wildflowers that sprout from a seed with the winter/spring rains, grow rapidly then flower, produce seeds, then die -- all within a period of a couple or a few weeks. It's all about genetic replication, and the expenditure of energy to do so. You save up everything you can in a "bank account" of energy, then blow the whole wad at once, and fade into organic bankruptsy (i.e. death). But if your genes live on through progeny, it was worth the investment.
Humans put a lot of energy into sexual reproduction, but I'd say that it's women who must invest far more than men do. That's why male bodies can afford to "invest" in muscle and size (the purpose of which is to be able to compete for females and the resources with which to support them and any potential offspring), while female bodies must conserve those aspects and instead focus on the internal use of energy to prepare for, nurture and give birth to life. A spoonful of jism vs. monthly ovulation, uterine preparation, hormone fluxuations, pregnancy, childbirth and lactation.Yet, women on average live years longer then men. Doesn't seem an even distribution, eh?

It's basically an energy that is involved in cell replication and is normally dispersed throughout the blood and entire body but during sex the Prenatal and Postnatal Jing are brought down into the male's genitals in order to help the sperm and egg begin replicating if conception occurs. Prenatal jing is related to stem cells and cell death. The taoists believe that there is a limited amount of times the Key can be duplicated before the organism begins to decay and die. Loss of prenatal jing is another time that replication must occur, and the loss of Postnatal jing throughout the body in order for the male to have sex means a lack of growth and healing in the rest of the body until it rebuilds.
Actually after masturbation us men don't feel "spent", actually invigorated as the Yang is raised up, it's after sex with a woman (especially at night) that we feel exhausted from gaining the woman's Yin, the woman taking our Yang (you feel awake and energized), and we get a huge melatonin (yin) dump and can't help but to pass out. - so you know.
