Anal Sex, Lube and Foreplay

In this world (due to religious, cultural, societal and female dietary reasons), anal is the most common form of sex. You don't need to apply a bottle of lube in order to fuck a woman's asshole since women evolved thousands of years ago to produce a substance similar to it naturally via a Lube Gland in their anal cavity.

Also, foreplay isn't really necessary since women are always wet & ready to go. It's also not very practical for obvious reasons.
