But I think that in such games it is necessary to reconsider all resource strips and their interaction (HP, mana and excitement.
I think so:
1) Leave the mana bar as is.
2) In some games we add a rage bar (for applying physical skills.
3) The most important thing is a strip of some kind of endurance - or hidden magical endurance, it is spent on restoring HP when necessary (for example, when the bar of HP = 0 and mana (you can heal with mana, of course, if you are not knocked down and you have the necessary spell).
4) Divide the orgasm strip into 2 arousal and an orgasm strip.
Excitement makes it easier to achieve orgasm and reduces combat, skills, damage, makes you move slower if the bar is high, and can also make the character masturbate.
If a character's orgasm is blocked, then the stamina bar will be spent.
5) HP is spent only from the damage received, if it = 0 the character receives a knockdown and is healed due to internal strength. During a knockout, he can be raped, captured, etc.
If the stamina bar runs out, the character is knocked out for a long time (loses).
