Dexcom placement

I know I should really know this but where is the best placement, anyone got any recommendations? I have more muscle than fat on my arms and legs and not that much around my waist now. I have a bit of what I would call a "fluffy" area on one hip my right, no idea why but as I am a side sleeper I think it would be a problem on either side to be honest. I have tried in the past with Libre, on the outside area of my arm and it caused me to have sore skin and again not much fat there now. I am having to use barrier cream as my skin is so sensitive. Anyone tried the tummy area? Many thanks in advance
