This job could potentially change someone for the worse, too. Confidence and arrogance are two different animals. If that's an issue make sure you aren't walking around like king dick just because internet pervs wanna bang you lol. It could also be bad for your psyche if you yourself FEEL like you're doing something wrong. I know a lot of girls who had to quit because they couldn't handle the way the sexual nature of the job made them feel. They spent a lot of time being stressed out, nervous, guilty, and worried about other people finding out that they were camgirls.
Basically dude, if your friends are telling you you're being an ass hole, you just might be acting like one; if they're misunderstanding the new confident you, or the new uninhibited you, or whatever you want to call the girl who has no shame where shame isn't due, tell them what's up. good luck (:
