I’m left-handed too, and I learned to play right-handed just like you. I switched to play guitar the lefty way too. It felt more comfortable to me, though the first time it felt weird. Whatever feels comfortable to you, do. Left handed feels more comfortable to me, but whatever is comfortable to you.

Hope this helps.

It depends on why you would want to change. Is there a reason you need to change? If so, change. If not, why bother.

I can play either way. Even though I have done that for 40 years, it can be confusing to switch back and force.

There was a time when I hurt my left hand and could not play for over a year. When I started playing again, I played mostly left handed until my right hand finally healed enough. Then I switched back to playing right handed.

For me, I can do more with my left hand than my right, that works better for fingering the guitar. I play almost entirely right handed any more. I can play left handed and did to show a nephew who was left handed how to start playing. Other than that, I find no reason to play guitar left handed.

However, I should add that I always play the bass left handed.

It probably would be quite impressive if you learned both, but that’s up to you and whether or not you think you’ll receive some kind of benefit from playing both left and right handed.

Thanks for asking!

You actually have a small advantage
since you have more dexterity in your left hand
which is the one that does all the fingering

and, as the above post mentioned
you will have a LOT easier time finding guitars
