I know that I'm a bit late to the thread (and I only joined this site to reply to it so I have no idea about mumsnet etiquette; apologies!)
Okay, so I've seen a lot of arguments about exploitation, immorality, false consciousness (phrased as "misguided choice") and such, combined with a lot of people who have clearly never participated in webcam work themselves dictating what a webcam show entails.
As somebody working as a camgirl (heaven forbid), I absolutely must dispel a few of the myths circulating here.
I am a recent graduate (first class, in case you were wondering) and am interning at a women's magazine (I want to be a feature writer/journalist). My parents are still together, I have never been bullied or abused, my self esteem is bordering on arrogant and I am a smart person.
I have been webcamming for about a year now, and I am totally happy with it. In the past, I have scrubbed dental equipment, waited tables, served drunken louts etc. for long hours and minimum wage. None of these things made me happy. Webcamming, however, gives me the money to pay my rent without compromising on the time that I invest into my internship. It pays well, makes me happy, and I don't feel exploited or degraded in any way.
I never get nude; in fact, I have never even showed so much as a nipple on the site. 60% of my tips (earnings) are the result of me sitting on cam, wearing casual clothes (t shirts etc.) drinking wine and chatting away to the people that visit my 'room.' I can earn more money having a laugh and a joke with men than other girls earn by anally masturbating, and that is simply because I allow my wit and intelligence to dictate the tone of my room: I make it obvious that I am not going to get naked for peanuts.
The other 40% of my income comes from domination and fetish shows. This means that I provide sexual services (the men cum) without getting naked or indulging in 'dirty talk.' I charge £20 for ten minutes of 'small penis humiliation' (insulting a man's penis and telling him that he has never satisfied a woman). Other sessions see me pointing the webcam at my feet and telling the client that he does not even deserve to lick them clean, laughing at a man penetrating himself with a hairbrush, and admiring a crossdresser's choice in lingerie.
I am not degraded, I am not immoral and, most importantly, I am not the exception: I am the rule.
Sexual exploitation and trafficking are totally separate issues and should absolutely not be conflated with webcam work (oh, and if a married man watches a webcam show, the camgirl is not to blame at all, he is).
