This is something I’ve realized since I was 12 years old (the first time I ejaculated).

Here are the symptoms I have:

Intense fatigue Brain fog Unable to concentrate on anything Gym performance decreasing (-20kg per exercise on average) Social “autism” 0 energy Doing the dishes, for example, becomes a chore

It is indeed ejaculation itself, whether WITH or WITHOUT pornography. Note that all other factors are identical (diet, sleep), so it cannot be an underlying problem related to fatigue.
