Just do it! Most venues have a beginner class that is specifically designed for people who have never danced (there will likely be others in the same boat as you). I started a few years ago, now I teach it and it's all I do in my spare time. It's also a great hobby because you can either go all in like me, or show up once a week for 1h and still have good time, meet people etc
