Totally agree with everything here! Some suggestions I'd make for upping your confidence though: Develop a persona for sexy pics/vids, etc. Because the thing with cam is, 99% of the members in your room are never gonna know *the real you*, beyond what you show or tell them - and even that can be faked, embellished, etc. etc.
If you don't feel sexy on video? That's cool, it's not too much of an issue getting started. But if down the road you feel like you aren't making enough $ from photo sales alone? Create a cam girl persona for yourself who *is* into video, or who at least isn't hella nervous about doing it (I totes understand where the nerves come from though!). I guess you can think of it like playing pretend, or real-life roleplaying. Decide who you want to be on cam, & fake it until you make it.
As for sextpanther, I think you have to have a decent following on social media (Insta, Twitter, Snapchat) and a cam model profile as well. I wish I knew what the exact number was, lmao, bc then I'd tell you. I just tried signing up for it myself, so we'll see.
