I know it, but I don't know numbers. Mb there is some way to see the game code, because I saw it several times, but again I don't know how to do this.
https://github.com/OXOIndustries/TiTS-Public is the publicly-available source code; most of the important stuff is in /classes and /includes. Note that it's over a year out of date and won't be updated until the JavaScript port is finished. As for how libido affects lust gains over time (which is what I think you want to know):
Code:
var prodFactor:Number = 100 / (1920) * ((libido() * 3 + 100) / 100);
This is Steele's base lust gain per minute. Various other factors modify this number before it's added to their lust, but none of them are affected by libido.
Libido also affects two other things: sexual endurance, and tease skill. For sexual endurance, high libido Steeles can often keep going after low libido Steeles get exhausted. Tease skill determines how accurate and damaging Steele's tease attacks are; it's equal to Steele's libido (capped at 100) unless they have the Ice Cold perk, in which case it's 100 - libido.
Has the Breedwell max cum quantity been decreased? I thought it was 20,000 liters but my 5,702-liter max cowgirl Nora keeps getting the question of whether or not she wants to blow the tanks apart while she's in the milker room.
It's actually 10,000 litres. As for how the cum quantity is calculated, it's either your current cum amount or three times your probable ejaculation (both as listed in the Codex), whichever is greater. 3*5,702 L = 17,106 L, which is more than enough to blow the tanks.
