I see you mate but i got to disagree on some parts. One does not get "friend zoned" because one stutter, its because one is insecure. Im in kinda the same situation as you as im tall (191) and work out some. I have a pretty heavy stutter but many of my friends call me one of the most outgoing persons they have met. If you choose to believe the stuttering makes you insecure it will, but i promise you mate only you decide what it does for you.
