You should consider launching your own web page. It doesn't involve any formal training or much effort. Check out YoU TuBe for directions on how to set up a web page or check out a commercial webpage that get you up and going! Most even help you register a domain name and some offer a web hosting service. The cost of these is relatively low and even though you don't have a financial interest in camming, setting a small subscription fee could help recoup some of your costs. An alternative to setting up your own site is to sign up as performer on a site like OnlyFans, Hope this helps.
Chaturbate is the place to go,free with plenty of viewers both male and female.
Have you tried VK? It is like FB, but much more lenient about "adult" activity. They have groups - you can do "live streams" that all your followers could watch.
If you decide to try it out - look me up!
