I’d really emphasize trying to attain mutual eye contact and back and forth smiling as you want to get their attention first; then, they may perhaps even be the first one to initiate the conversation. Also, don’t underestimate the amount people attribute to mere anxiety. For example, people might often interpret blocks as someone trying to ‘collect their thoughts’ and a repetitive stutter as someone that is nervous. This isn’t a HUGE turn off for most(and for the ones that it is, they’re not keepers anyway) If you are still deeply unconfident about approaching women in person, online dating is always an option. often times, a better option since you can meet someone online(where speech impediment is of no concern), form a bond with them, and then gauge whether they’re the kind of people that are accepting enough to still see the myriad of good qualities you have beyond your speech impediment. Good luck!
