You can get your own webcam and website, and/or set up a chat site (interactive).
Or you could set a camera up in your room all day and night (or certain hours) for subscribers to check in anytime while you just do what you normally do (voyeuristic).
Be warned that anything you put out there will potentially be in cyberspace FOREVER.
So be careful, decide on your own boundaries, and stick to them.
If you don't want to show your face or otherwise disclose your identify, there are tons of creative ways around it.
