The only people who have answered correctly have answered (generally):
Do I want to make my favorite past-time my job?
The rest of you FAIL.
If you did your research, you would know:
A) Gay actors are in demand. You want an income, you better acquire a taste and a happy face for cock.
B) It's unbelievably hard to be (even a qualified) porn-star. Unless the studio is looking for something freaky/niche market, you must look like a greek statue. All muscle, no marks, no hair.
C)Most studios want at LEAST 7 inches of cock. That's most likely 1 inch more than what you have. Once it's on the internet, it stays there and you receive all the taboo/scorn that comes with having your naked form available to everyone.
D)You must be able to get hard, stay hard, and ejaculate on command...
In front of a studio full of people!!!
(What really pissed me off was the thing earlier of "I'll only do it if there's one girl and the people leave". Grow up)
What stops me is "C". Otherwise it's the correct answer as mentioned already.
