1. Why do porn VHS tapes come in such freakishly oversized boxes? No one has been able to give me an answer to this question.




VHS tapes are fragile, so lots of surrounding cushioning keeps them from being destroyed by shifting and banging during shipping.

2. What is with a lot of scenes in gonzo videos being filmed in warehouse settings?




Most porn companies have warehouses, so they can shoot on their own (private) property without film permits or other hassles.

3. What makes alt. porn so much more "alternative" than other porn out there?




Nothing. It is fun to stigmatize those with non-mainstream preferences. Just like in all other aspects in life.

4. My friends raided my porn stash and acted appalled by what they found(JM stuff, Max Hardcore, ect.). They asked me why I don't just watch normal porn. Is any type of porn actually all that "normal"?




Anything not bukkake or donkey punch might pass as normal. They probably use "normal" meaning having E! network-friendly stars liek (yawn) Jenna Jameson.

5. Does anybody have any answers for these question?




Not really. I figured I'd waste a few seconds of your time and up my post count by one.
