your dna assigns you a fixed amount of calories
False. Calorie Restriction does not work that way.
> semen internal reproduction and external production can be the most taxing thing on your body
LOL no. There are generally about 300-500 million sperm cells in an average load. That's not a lot, about 2% of the total volume. The rest is water, fructose and nutients (all of which is excess from your diet).
It takes more energy to maintain things like your hair, skin, and fingernails than to generate semen. But the kings of energy consumption are the brain, heart, and lungs. The brain alone accounts for 25% of the energy consumption in the human body. Well, maybe not your brain.
As far as "taxing", if you've ever been to a gym, you've done more damage to your body than a month's woth of fapping. Also, any woman who has had a single period, let alone gone through pregnancy, would like a word with you.
your caloric v endorphine ratio must be taken into consideration
What the fuck? Meaningless bullshit.
