As a previous answer said. The truth is that yes, it makes you loose points on the attractiveness scale. I was always self conscious about it, but when I gained a lot of confidence, owned it and joked about it, 2 girls (that later became my girlfriends) told me it was charming. And one of them told it to her friend without me knowing (saw the text weeks later). Of course, my stuttering is not super intense most times, but I still got my first GF only at 21 y/o. As a previous answer said, a high confidence stutterer will accomplish more than a non-confident non-stutterer. You just have a lot of work to do on yourself (also on your anger apparently). Keep your head up. Good Luck
