My boyfriend stutters and I don’t find it unattractive. I was never turned off by his stutter and I always reassure him that it’s never been a problem for me. I think it is true women are attracted to confidence but there are some women who appreciate vulnerability as well. It was very attractive to me that my boyfriend was able to share that he is insecure about his stutter but also drove it home that he is working on his confidence towards it, not just giving up and letting it rule his life. The point is I think the vast majority of women do enjoy confidence but I don’t think you have to love your stutter 100% yet. It’s also appealing to be around a man that accepts his “flaws” (I don’t see his stutter as a flaw but he does) and approaches them positively with a goal in mind for the future.
