I am kind of trying to make some money online as I live alone, I have no sponsors, no family, minimum wage job and I am trying to finish my uni... somehow. The point is, that If I could make at least something, it would really help me.
I'm sorry to hear about your current tough situation. Trying to stay afloat with a job that doesn't pay well, coupled with the steep cost of uni, means you might need to think beyond just variations on old-school porn sites.
There are people making good (and in some cases, very good) money modeling in adult video-cam entertainment, where the start-up and overhead costs are low and the hours are incredibly flexible because you determine when, and how often. Chaturbate is one cam site that comes to mind. Many men and women begin with the modeling as a second income stream, and the ones who excel gain their principal revenue from it.
You mention that you have no immediate family and live alone, which is plus in this scenario. But if you live in a country where being identified risks your life, then cams absolutely are not an option. If your uni is religious and you don't want to transfer to a public option, cams are out, as well.
Cam show performers often develop niche audiences for a specific (and yes, often fetish) performance style. As well, to be frank, cams are ideal venues for performers with faces and bodies that are less than perfect.
While some cam models have the boilerplate, muscular look, many others have a single exceptional quality -- beautiful chest hair, big OR tiny dick, uniforms, painted toenails, verbal style, swinging testicles, piercings, obese and proud -- if you can imagine it, there's a market for it. And significant revenue can come from the "private show" options, so a few recurring patrons can mean a nice income stream.
To sum it up -- a cam is clearly not for everyone
, but it's an option for some.
