Similar boat for me. Girls have actually approached me, but I shut down out of fear of what they would think when I spoke. I probably just came off as a rude asshole because very few people realized that it was because I stuttered; that basically killed my college years. In retrospect, I was both right and wrong. Based on how I was treated when I did stutter, I'm sure some girls would have just blown me off. And that sucks, but I'm sure others wouldn't have too. But none of that was worth not even trying. I'm your age right now and I'm hoping to turn it around. No use thinking about what could have been in high school, that's long gone. What's left is to just look forward now.
