A quick poll of a few porn stars up at 8:30 in the morning reveals that, in addition to being porn stars, all have separate sources of income, including dancing and escorting, but also work that has nothing to do with boobies.
"I'm a webmaster."
"I collect alimony."
"I sell hydroponic pot."
(The last one is iffy. If you've ever tried most versions of hydroponic pot, perhaps boobies would help to make the sale agreeable.)
But I always thought that once someone was paid for something, he or she became professional at it.
Unless "amateur" refers to quality.
Backdoor Bangin' is an amateur anal title from someone named Aaryn Star. I don't know Aaryn Star. I don't know how he earns a living. But if you marry him, Connie, you'll disappoint me.
If each of these women was paid for her work in this movie, how are they amateurs? Is it because they haven't been in many films? If so, why aren't the women of, say, Barely Legal called amateurs?
If the women were paid, then I think a more fitting way to describe this movie would be "amateurish". That would explain why a clip-art front door is on the cover and why some of the ladies don't have that porn glow about them.
