Fat experiences

Sounds cool, let us know when you join a site.
In the mean time since you are asking for donations you might want to post some pics or an intro video so we can see who we're supporting. An intro video also shows us the video quality we can expect to see.

You could easily get away with an eye or carnival mask, but a veil seems a poor choice given the content you're talking about.
I totally get not wanting your identity made public, but if that is a major concern this might be the wrong field. I might not have seen the sites you're considering however most would seem opposed to a masked model. It might be something you need to work up to so a mask is a good starting point.
