Im 20 M , had no issue with any females disrespecting me because of my stutter, in fact they respect me even more when I disclose it to them. Always had great experiences with them being patient. Not once have they made a complaint about my speech in a negative way. Trust me, as long as you have confidence and your charming and respectful to them. U will have no issues. Also, u shouldn’t be worried about girlfriends. Focus on urself, elevate yourself to the max. Get better each and every day. And they will automatically come to you. God has a plan for you. Psalm 37:4 God bless you brother, if you need anyone to talk to when your struggling. Don’t be shy to shoot me a dm.
