Tbh bro, i feel like a cold in-person approach will rarely work for a stutterer. 1. Because they’re gonna be attractive so you’ll be nervous and 2. The girl will think you’re more nervous than what you are and they’re more likely to say no. Have you tried online dating? It’s the easiest way in my opinion, you can communicate and meet girls without physically speaking to them. If it’s going well you can ask them out for dates and disclose your stutter beforehand.
