My wife has had an iPhone 6s from day one and I've showed her what 3D-Touch was but she hasn't used it once since. Whenever I use her phone I never use it either - it seems unnatural for me to press harder on a display / touch device. Most people outside the geekiverse don't care for it either as far as I was able to observe.
I'm with you. It's not a natural motion. Seems forced. In my experience nothing I do on my phone would be easier by using 3D touch. And I often forget about it. When iOS 10 drops I imagine I'll give it another try. When I first got my 6S I tried to use it consistently then I just stopped at some point.
