T-girl sites are the fourth most popular category of adult Web site

I'd guess Lesbian,straight, and gay are 1-3?...what would be 5? Is there a five? Is there an actual list or something?

Midgets I'd guess.

No one else has input? This is a thread calling for Franklin's expertise, if othing else.

I'd say it's either interracial or MILFs.
