theres nothing wrong with being left handed generally though there are certain hands for certain things.
Hafsah radhiallahu anha the wife of the Prophet :arabic5: reported that the Prophet :arabic5: used to use his right hand for eating, drinking and getting dressed and his left hand for everything else
Abu dawood
Al-Nawawi (may Allaah have mercy on him) said:
“This is a fixed rule in sharee’ah. It has to do with honourable things such as putting on one’s shirt, trousers and shoes, entering the mosque, using siwaak, applying kohl, … combing and styling one’s hair, … shaving the head, giving salaam at the end of prayer, washing oneself in ghusl or wudoo’, leaving the toilet, eating, drinking, shaking hands, acknowledging the Black Stone, and other things where we are encouraged to use the right hand or start with the right. As for the opposite [things that are not honourable], such as entering the toilet, leaving the mosque, blowing one’s nose, washing oneself after using the toilet, taking off one's shirt, trousers and shoes, and so on, then we should start with the left or use the left hand. All of this has to do with honouring the right hand or right side.”
