What are my chances at starting an OnlyFans as a 19 year old Man with a big dick?

So I am a university student and therefore rather short on money as most students are. I am 19 cm in length and have width that cannot fit inside anything below a condom size of 72.
I've talked with a friend of mine about this and he even told me i have that twink type of build. I would not show my face and don't even expect to get rich out of it, just to help me get through my bills with maybe some spare money if possible.
Now I would like to know, how saturated is the market in that regard? How are my chances in that field? Are there lots of male creators with sizes like mine or even bigger? Or can I heavily profit off of my circumstances by being “rare”?
I am not trying to flex or anything, it's just that google and a friend of mine told me my size is very untypical to have. I kinda feel like I'm wasting my potential by not doing anything with it.
I do not watch conventional porn and therefore never got confronted with penises, i only found out about my unusually big size about 2 years ago.

I would also like to know: What would be the audience? Women, gay men? 
Should I wear a fursuit for more customers or would that shy away the “normal” ones? Would a mix of both be smart or counterintuitive? 

Thank you in advance!
