ATLust will track several types of body fluids. Each type has its own special properties and uses. Fluids can be transferred from one character to another through physical contact, and this is also how STD's are spread.
Fluids on external organs can be cleaned up with the wash cloth items.
Fluids have lubricity values which helps to lower the arousal costs for sex actions.
