I don't actually clearly remember the first time I appeared nude on cam. I think it was with my fiance for a sex show--our first one obviously, on chaturbate. We did pretty damn good for not knowing how to take advantange of bots and apps. Got 7,000+ viewers and a decent amount of money. Probably could've made a lot more with an app or bot in place though.
Anyway, it felt... fun? I didn't feel nervous at all because my fiance was sharing this new experience with me, so I didn't feel alone and exposed wondering what I should do or say. We had decided to just have sex on cam. Simple, easy. If we got viewers and tips, great, if not, then we'd try something else another time. It felt pretty natural and normal, really. I was able to ignore the fact I had a virtual audience pretty easily despite having to move the webcam around a bunch of times to get some good shots. Afterwards, I felt a little shy and thanked everybody who watched/tipped. Thankfully no one was rude and everyone seemed to enjoy it, and we did get paid a decent amount, like I said. Nothing crazy, but it was something for first timers.
My first time getting naked solo on cam was a little stranger because I had to think of things to do and say. I liked to just use a tip menu in the beginning, so I wouldn't get naked unless people tipped a certain amount for a certain act or whatever. I don't remember how well I was paid my first time getting naked solo on cam, though. It wasn't anything spectacular, but I also was new at pricing things so my tip menu was pretty cheap to start off. I felt totally fine taking my top off, alright with taking my bottoms off, a bit shy about showing my kitty, and really shy about actually using my sex toys, but if a customer paid for something specific I would do it regardless of my nerves. I just dove in and ignored my bashfulness. It's really easy because you can't see your audience or hear them, which was conducive to pretending I was alone and no one was watching me. I don't get off on being watched, to be honest.
After the first couple of times getting naked on cam, I basically became an exhibitionist. I'm really comfortable with getting naked for the camera now, which was made easier by my previous freelance modeling experiences that included partially and fully nude photoshoots. I eased myself into it with boudoir photography, teasing with nudity at first, then going topless, then finally bottomless for pictures over a period of a couple of months. Those photoshoots made getting naked on cam A LOT easier for me.
