Stuttering in front of girls is very necessary. You can’t hide it forever. I’ve found that some women actually find it endearing, oddly enough. Something more important to show a girl is the fact that you try and work on it, and that you aren’t ashamed. That’s admirable. People like when their partners can overcome obstacles. Use it in your favor and embrace the challenge. Easier said than done, but it’s worth remembering! Good luck :)
