Confidence is applicable to courtship. I would add though, being comfortable with it and yourself defeats all hang ups you or others may have about it. And with that comes confidence in a cool albeit roundabout way. Owning who you are as a person is the best way forward from my experience. I had a period where my stammer was so bad that I essentially became a mute and I still had great times with trying for a relationship. I can understand it’s easier said than done but accepting it as a part of yourself and being open about it is confidence in itself! Hope it goes well for you!
