I'm 23, have struggled with a mild to moderate stutter my whole life. My advice with the girls - just own it. You are gonna stutter sometimes, it's just a part of who you are. It in some ways made you who you are, so don't act like it isn't there around people (girls) you want to impress. I really had a hard time my first couple years of college, but once I found my inner confidence in spite of my stutter, it stopped seeming important in the scheme of things, like the rest of me far outweighs the small fact that I stutter. Most girls find it adorable or don't even notice, especially if you don't let it hold you back in any way. (and by most I mean 99%) I am saying this because I don't want you to let it hold you back. Actively mold yourself into a man, use your youth with energy and vigor, not fear of the unknown or a stutter, and you will slowly realize that stuttering is only as significant a part of you as you let it be. One last note - working out has been a big help to me. Something about increased testosterone levels really pushes my speaking confidence through the roof. Best of luck friend, I have felt all the pain and frustration that you have, but there is just SO MUCH to life beyond a stutter that it really seems insignificant after a while, if not endearing :)
