I would like some porno grind like spermswamp http://www.youtube.com/watch?v=oaWfCTuVhH8

things like Porky Vagina and Satan's Revenge on Mankind would be great too.

I don't know much about porno and goregrind so I am hoping you guys can teach me a thing or two.

Gut are the un-sung masters of porngrind. Cumbook has some decent stuff they put electronic in it though so you've been warned, definitely check out Gruesome Malady too, I see them as sort of a sister band to Gut, Oh also check out Gore Beyond Necropsy, they are beast.
I also recommend ArseDestroyer, they're getting into noise territory, if you like them check out Last Days of Humanity, and then maybe
browse around this sight,http://vaginalapocalypseproductions.blogspot.com/
Oh I forgot Full Frontal Face Fuckers, they're a lot like GBN but with a more Autopsy flavor and they are obsessed with porn.
This sight was rec'ed to me on another forum

You might like S.M.E.S., I've always thought those and SpermSwamp were quite alike. You might also like Urine Festival, I know I do! Crazy fast cybergrind with bubbly vocals and shit, it's great. Also there's stuff like Libido Airbag and definitely Prosthetic Cunt. You mentioned Satan's Revenge on Mankind, so I'll recommend Kringspiertyfus, Hymen Holocaust and Corpse Carving.
