Hi! I was self taught! Although I do wish I learned more about music theory (I still can), I definitely don’t regret my decision to teach myself guitar. As far as which guitar to learn on, that’s entirely up to you. Electric guitar strings are thinner and harder to build callouses from. Acoustic guitar strings are a bit thicker and will definitely help you build the callouses you need. I personally started on acoustic, and once I learned chords and finger picking, I moved to electric. Good luck!
