LINK quote [The Porn Industry in Los Angeles is booming. New actors and actresses are always coming in and out of the business because its life is so short-lived. People don't wants to see the same faces all the time and for the girls, as they get older, they get less work. Also, they can't work as much as the males do, because it can physically hurt them, especially when it comes to being fertiles. For men, there are only a few big porn stars because most men are not able to perform under the "pressure" again and again on a daily basis, so most men try it once or twice and leave soon after].
