1) Is Onlyfans considered sex-work? Why?
Onlyfans is technically just monetization platform. Not all creators perform sexual related content (probably less than 1% however).
I do think that any person that performs anything sexually/erotic related and gets paid for it = sex work , regardless of the platform.
4) How does one go about looking for a someone to do onlyfans with? Is this what they call the power of social media?
Good luck! Pretty sure models get hit up a lot by people wanting to do just that all the time. I remember some interview a while ago where a porn producer was explaining how few guys can actually perform in front of the camera on a production set. So unless the guy has a proven track record (ex: successful content creator), you're probably going to be SoL (shit out of luck) or end up as a blooper on Efukt. Perhaps if you see a SP that also does OF content you can discuss it with her?
5) Who is the Ron Jeremy of Onlyfans for the new generation? Why?
No idea. "The Hedhog" was never considered attractive, but he had a big dick and could perform on command. He was considered more like a circus freak than a performer and you could tell girls weren't exactly thrilled to do a scene with him. This at a time where porn production was quite underground probably wasn't easy to recruit new male talent. Boogie Nights starring Mark Wahlberg comes to mind.
In today's world, I think the entertainment industry really ignores those that have unnatractive features unless they have spectacular talent. It isn't rare to see them be physically transformed following their success. How many Freddie Mercury types won't make it because they don't fit a certain beauty mold? or Adele or Susan Boyle? Sadly, not surprising that all music and movies look and sound about the same or some remake targetting a new generation.
The same can be said in porn. Apart from some really well known guys like Johnny Sins, Keiran Lee, James Dean, Manuel Ferrara, Rocco Siffredi, etc... all whom have been around for a LONG TIME, can you really say that you notice the new guys all that much? Seems like they are all the same now, just some stunt dick filling a spot.
As for having an ideas, everyone has them. The real skill will always be the ability to execute them - "The cemetery is filled with great ideas". Also, just because you find it great, doesn't mean it will be successful but hey, you can always submit your ideas and see what happens. Montreal being the porn hub it is, shoudn't be hard to get in contact with someone. But as others have mentionned, its likely been done already and if its not easy to find, it might just not be popular.
