I know lots of people hate it when I post non-game stuff here, but I figure I just posted a whole thing on all the monsters starting with D today, so I've earned it.
Some confusion has arisen concerning nomenclature, allow me to explain:
Most people decide that they want to have sex with you before having sex with you
Whores decide they don't want to have sex with you before having sex with you,
Porn performers decide whether they want to have sex with you while having sex with you.
Note: Overlap has been known to occur. Some Porn Performers are known to never have any fun, and so are--practically speaking--Whores, while some have other sources of income or fairly high rates and so have the luxury of behaving like Most People.
For more information on porn stars and whores, visit your local library.
