There is one kind of video content I've never ever seen.
A time lapse video of weight gain. Make a picture every day or almost every day, in the same pose (or you can slowly rotate the pose), for years.
It would be very interesting for someone who starts relatively thin, to get huge over the years and make a time lapse video. It seems no one ever did it.
There are time laps videos about pregnancy, and about growing hair. But about gaining weight, there aren't any.
You can become the first one in history to do it
And it would be a welcome addition, as videos seem to have much less variety than pictures. In the pictures section there is a wide variety of poses, styles, clothes, situations. In the videos section it seems 99% are just about rubbing your own belly from a close-up view, and the rest isn't really diverse either.
