Its not well known, but most of the women in the porn industry are not beautiful to begin with. For example, Asia Carrera is one of the top asian porn actresses in adult entertainment today, but have you seen what she looked like before she entered the industry? The thing is, there are many different artificial ways to "beautify" a woman. The general rule when it comes to woman is that either they have great breasts and a fat ass, or they have a fat chest and a great tight ass. Thanks to the marvel of modern technology and biotech, you can now turn any ugly woman into one hot babe. All that you need is a woman willing to go through with it. When you look at it, being in the porn industry means essentially means throwing your morals out the window to make lots of money for doing virtually nothing.
The general trend is that a regular woman makes a movie from some of the less famous porn production companies, uses that money to alter her body in some way to make her body more sexy, then makes another porn movie from another, "more famous" production companies(or the original one), makes a little more money, alters her body some more and the circle repeats until you get to the top porn producers like Vivid or Valentine and makes the big dollars. For example, Stacy Valentine pre porn actress and Stacy Valentine post porn actress looks very different. She didn't have many plastic surgeries, but she's gotten breast implants and liposuctions to get a more desirable body because her original body is hardly sexy.
The porn industry spends very little for the setting and special effects in comparison to non-adult movie industries, where the filming set represents a significant portion of the cost to make a movie, so a porn production company can afford to make like 10 to 30 movies in one year in contrast to a non-adult movie production company and they can also spend more to "beautify" their porn actresses.
So in reality, you don't need to pick up excellent macking skills because you don't need to pick the best HBs to make your porn movies because you can use modern technology to "beautify" them.
