Hi, many folks see photos/videos as a harmless way to make an extra buck or two. If you aren't worried about them being around forever, then there's little to stop you.
You do need to make sure that your clients cannot identify or locate you, some people feel very entitled no matter how little they pay. I'm no expert, but I would imagine that the easiest, regular money is for someone who feels a close connection to you - that may relate to personalised content such as wearing a particular colour, eating a specific foodstuff or referencing someone - or because you provide a unique image such as showing the soles of your feet or moisturising your hands.
Once you cross the threshold, you can't be squeamish if a vulnerable person is spending more with you than you think they can afford and once you've taken money for sex work, you are a sex worker.
To my knowledge, I've only met one prostitute - she was a lovely, caring person and I didn't realise what she'd told me until the following day - I'm sure that she saw herself as more of a carer.
In the world of porn, you can see that a very small minority make a lot of money from selling their personality, are clothed more often than not and stay around longer. Conversely, many are chewed up and spat out after forcing very large objects in very small apertures.
Something like self-bondage or smearing custard/cream on yourself is the kind of niche that wouldn't require showing your face, but I'm sure you'd need a hook to keep fans loyal.
You could of course imagine yourself in this role and write a 'memoir' - if you look at the creative writing threads here, porn-writing is often recommended as the quality available is apparently dreadful.
It's a tricky world out there, I hope that you navigate it successfully.
Be lucky, but sometimes online surveys and stacking shelves have much to recommend them. I'd love hear what you decide to do. David
