Not sure what site your on at the moment (im looking to add a new site so if you dont mind, let me know or message me the name and how you find it there), but I have been on chaturbate for 3 years, it's up and down. I'm not a top model but most month's I make enough to get bills and rent paid, having 3rd party sites set up is a big help to be honest though. There's a lot of traffic on chaturbate, but for guys one of the biggest issues I have noticed is that because of the amount of exhibitionist cams people expect shows to be free or pay what you want. Recently tips and shows have only been about 30% of my income on chaturbate with the other 70% coming from video sales.
I do know a couple of other male models that do pretty well and have a dedicated enough fanbase that their earnings are fairly constant.
I would say give it a go, what is there to loose?
