You central nervous system will get an instant recharge by orgasm to command your pituitary and the other endocrine organs to produce more DHEA and testosterone and you won't feel tired and exhausted IF the ejaculation can send the orgasmic energy back to your central nervous system and pituitary using your energy water pathway - the spinal cord.
The problem is the orgasmic wave energy has to pass through the periodical structure of the spinal cord which produces resonant (Bragg's) reflection of the orgasmic wave train. That is, only a small amount of orgasmic wave energy can reach the brain. Generally speaking, to repower the brain function upon ejaculation, you have to accumulate a lot of sexual energy BEFORE orgasm.

Sex and masturbation are 2 completely different things.
In sex you extract sexual energy from my partner's to power your penis to maximum size(that is when you feel your penis going numb or semi-numb with a massive erection - then you know the sexual energy stored in the prostate and penis is maximum). When orgasm occurs, contraction of the prostate muscle sends a powerful orgasmic wave back to my brain that stimulate your central nervous system and endocrine organs - adrenal cortexes, the pituitary, and testicles. After a sex like you will be surprised to find out that you are not feeling that exhausted or tired. This is because the endocrine system has been re-powered by the massive ejaculation orgasm. Masturbation cannot help you achieve that kind of recharge.
You should not masturbate until experience the pelvic congestion due to over-accumulation of the by-product of testosterone burning -DHT(dihydrotestosterone) in the prostate area.
