My stats?

"What do the statistics on the side of my screen mean?" you ask.

Health: Your ability to take physical punishment and keep fighting. Wounds, bleeding, bruises, starvation, suffocation, etc, all bring down your health. Short rests allow a tiny amount of health to be restored. Sleeping through the night will replenish much more.
Being reduced to 0 Health during combat will trigger a special lost combat scene, depending on the opponent. Depending on the opponent and other factors, that also may lead to a capture.
Restorative items can be found and purchased that can restore lost health.
Stamina: Your energy reserves. Every hour spent awake depletes this a little. Combat depletes it a little more. Attempting to escape from combat uses more than that, and below a certain stamina, escape becomes impossible. Some special combat maneuvers require a certain stamina level to perform, and some items may use stamina as a resource. Traveling in the wild with 0 Stamina is very dangerous, as you can collapse from exhaustion, and possibly suffer at the hands of some enemy, or even be captured.
Short rests recover a modest amount of stamina. Sleeping through the night recovers a large amount.
Libido: Your lust and sex drive. The corruption of the Untamed Lands is insidious, and causes all living creatures to desire sexual activity more than usual. In combat, having high Libido opens up special tactics for many opponents, and maxing out during combat leads to a special lost combat scene, and depending on the enemy and other factors, may lead to a capture.
Masturbation and consensual sex can reduce libido with minimal downsides. Suffering **** encounters reduces it, but usually comes with other negative effects (lost health, increased corruption, etc).
There are special items that interact with your libido that may be found.
Hunger: Your need to eat and drink. (I've decided not to separate hunger and thirst). Increases steadily over time. When maxed out, you take health damage at regular intervals until you sate your need. Food can be found at settlements for a cost. (As long as you are able, food is very cheap on the Brighthome side of the Bridge of Pearls). You can also forage in the wild for sustenance, at your own risk. Rations may also be purchased that you can carry with you as you travel.
Corruption: The creeping taint of the Untamed Lands. It seeps into every living creature, with some more or less susceptible to it than others. Above 50% corruption, you will not be allowed to return to the Brighthome side of the Bridge of Pearls. High corruption opens you up to special attacks from many enemies. Orgasms outside the protection of a Calming Crystal raise corruption a little. **** encounters raise it more, as does submitting to an unwanted violation without struggling. Furthermore, the seed of highly corrupted creatures has a corrupting effect when taken in or swallowed, and even more so for the seed of demonic creatures themselves: succubi, incubi and imps. (Their seed is also intoxicating and addictive when swallowed) If Corruption maxes out, a mutation may occur. If too many mutations occur, a bad ending may be triggered.
There is no natural way to purge corruption. There are some magical plants that can be foraged or special springs that may be found that reduce it in small amounts. There are also magics that can purge it, but are rare and often expensive.
Gold: It's....it's gold...you buy stuff with it. You can earn it by taking jobs, or more...unsavory actions.

In addition, there may be hidden statistics.
