Ok i might be close. I have a pretty bad stutter and its about impossible to not notice within 2 minutes. I was in the luck of hooking up with a pretty nice girl on a night out, we hung together for about 5hours while both pretty intoxicated. It ended up at her house with some mediocre sex. As we woke up the next morning and started talking she gets this "oh shit" look on her face and start texting for a minute. A week later i found out she texted her friend just THEN realizing i stutter. I still do jokes about it.
