I also feel this way honestly , especially when it comes to conversation with girls. Im very introverted and anti social, sometimes by fluk I can get into a conversation but for not very long. My flirting skills are bad , can't seem to in the moment think of things to say and keep conversations flowing.. always run out of words..and yet in school, I was a top learner in English..but maybe it's just that I've not expressed myself rightfully as yet due to the stutter and avoidance all these years
