I think maybe these girls are a bit superficial. Rather than seeing your stuttering as an interesting quirk or facet about you, I think they just judged you. They don’t understand real love. I think they are just shopping for some Alpha male like they would an object, and discard you like an object they don’t like. As long as you are pushing yourself a little bit out of your comfort zone, you should be good. Keep going until you find somebody looking more to understand, or looking for actual love. Or someone that doesn’t see skipping one piece of expression or interaction as a complete failure of your manhood. Keep your head up man🙂✌️
