The stuttering alone won’t hinder girls from being with you. At least not all of them. I and countless other stutterer married. And my wife is very attractive and smart. There were other guys interested in her as well. But she chose me despite my stuttering. I guess she doesn’t mind it because I don’t mind it too much, even though especially during the time we got to know each other and became a couple it was very strong. A lot stronger than it is now. And that’s also my advise. You have to be able to accept yourself, be confident in who you are. Sounds cliche but it’s a fact.
