I am 24M having similar type of thoughts. I have decided to not marry and stay single for life. Acceptance: Till now I haven't able to fully accept my stammer. Why would some other person will accept it ? Genetics: My stammer is hereditary (genetically transmitted). I got it from my father and my father got it from his grandfather (mom's side). I don't want my kids to have face this pain / suffering. So, I have decided to break this genetically transmission chain by not to marry.
