Dude I am 30 y old female. I had a stutter since childhood. It used to be bad. It’s still frustrating at time but it’s not as big of a deal as we make it in our heads. A lot of your friends or family won’t even notice it after a point. And if you’re worried about relationships, I’m sure you won’t want to be with someone who’s that shallow that they’ll be conscious of your stutter. Hold your head up high and good luck. :)
