And, of course, the very instant you bring a dildo on camera, everyone is going to want you to shove it up your ass

Shyguy's exactly right. Dildos make great theatrics. That and trash talk will get you and your viewers where they want to go. But really, just get used to the inevitable suggestions/demands for "harder" "deeper" "Get a bigger dildo", (I hate that one), "gag on it" etc. Know the the things that your willing to do (or not) and stick to your limits.
