I'm writing an essay investigating the culture of selective
homophobia here in America (gay men are sigmatized to a greater extent
than 'lipstick lesbians,' who are objects of straight men's erotic
desires).

I would like to know:
a) How much money the porn industry generates each year
b) How much of that money is generated by content that is exlcusively
lesbian in nature
c) What percentage of the Internet is pornographic in nature

C puts me in mind of a quote by Dr Cox, the character on NBC's
"Scrubs" played by John C McGinley.

"I'm Fairly sure if they took porn off the internet there would only
be one website left and it would be called Bring Back The Porn."
