Funny porn, comedic porn can still be unfunny.
I'd say about 40% of stuff found on hentai foundry
would count as funny. Garabatoz, Sparrow, Akabur, Freako, and more. While the subject matter of their works doesn't please me at times (Sparrow drawing furry art, Freako with his turtle stuff, and down the line into other artists) I enjoy their work because it is funny. I just enjoy the humor, enjoy the deviancy, and if I get in the mood I'll enjoy myself more actively. However it's more about the humor than it is the sexual pleasure.
