What is being called "normal" here is "normal" for intellectual animals (that is, it is common for them). However, it is not normal for human beings.
Regarding "recharging," you should be aware:
Every action is governed by laws of nature. One of those laws is:
4. Once an action is performed, the consequence cannot be erased.
If you pull the trigger, you cannot pull the bullet back. It is the same with our thoughts, feelings, and actions. Once you have said a critical word and caused pain, you cannot take the pain away. Once you have struck someone, you cannot take away the bruise. The same is true for actions that you do to yourself. Once you commit a wrong act, you cannot take away that act or its consequences.
The vital energy that is lost in an orgasm is permanently lost. It also accrues consequences that must be dealt with karmically.
Depending upon its health and nourishment, the body will generate more sexual energy at a rate that is relative to its own circumstances. For instance, a young, healthy person will generate sexual energy rapidly. An older person who has abused the sexual energy for a long time will not generate energy quickly, if at all.
Every orgasm degenerates the system. Eventually, it will fail completely. This is very evident in modern society.
