Videos / pictures to SO

So has anyone ever taken a video of themselves for their S/O if so how / where do you do this and what do you do? 
My partner and I have been together a while now and he's mentioned it a few times and deep down I would like to do these things but I don't know how to go about it. 
What are other people's opinions on this? 
Personally I think it would be good for my confidence with myself and my body to do just to love the skin I'm in because I am so insecure.  I just want to feel sexy. Even if I never showed anyone.
But yeah discuss away ladies id love to hear opinions!
