when I was in school way back in the 50ths they used to beat left handed kids over the knuckles to try to change them.

They said you are deliberately being rebelious.

That did not work for me and im still left handed.

When I first started to learn to play guitar in the mid 60s there was hardly any left handed guitars around, so I started to learn upside down on a friends right handed guitar.

I managed to learn 3 chords G-C-D. but was having problems with strumming up all the time so I gave up.

Now there is hardly any guitar manifactures that do not make left handed guitars.

So stick with what feels the most natural.
