Hi there!
Well being a switch is awesome – gives you a chance to experience a wider variety of emotions and sensations. It’ll also help make you a better domme, no doubt about it, as you learn more about what is going on in a submissive mindset.
However, warning first. I need to check this is someone you know is real and genuine. Ideally, you’ve met them in real life, or if it’s just online… that you know 100% they are real. There are a LOT of fake femdoms out there, mostly guys cleverly pretending to be women, or just some psycho women pretending to be dommes. Much safer than a video is doing it on a skype call or similar, you can just tell so much about a person from how they are when you actually speak to them.
I raise the concern because you have to be super careful about sending anyone ‘a recording’ of anything that could be used against you. That doing that is your first task for them is a bit of a red flag, so you’re right to be nervous.
If they’re someone genuine they’ll accept you doing it for them as you chat or skype to start with. If you do do a recording make sure it’s anonymous, and that includes things like not showing distinctive furniture/room elements.
The main point though, is have fun with it, while keeping yourself safe. It’s really great to experiment with different roles. While I’m very much dominant in my online life in my marriage I’m so much more switchy, just because it’s a lot of fun and it keeps things fresh.
