Opening up to the camera

Hello everyone,
I'm new to the site and have never filmed my wife and I before, but would like to. Even though I've been telling her to charge our camera for quite awhile, she's been purposely stalling.

When we met she was in shape, so now she is self conscious about her body since adding some pounds. I was hoping some of the ladies who may have overcame this themselves could give me a little advice or guys if you were successful in making it happen.

Generally she is ok with trying new things in regards to toys, etc., it's just her body she's not comfortable with right now. I've already explained to her that how she looks is only one factor and that I love how she looks, feels, smells, tastes, etc. I think she'll come around, but open to constructive help.

Thanks ahead of time!
PJ
