's funny. all the people i know from college who've done
porn (either photographic or filmed) did it for free, thereby not getting a
red cent.
Philip Greenspun (owner of photo.net) once said something to the effect of: there are two types of people (in context of modeling): those who like to be photographed and those who don't. Those who don't like to be photographed are unlikely to take their clothes off. For those who do, it's hard to keep their clothes on.
porn can be fun.
