When you see the old jokes of “guys with long hair being confused with girls” on tv shows like drake and Josh and just have the feeling… “that would be fun, you know to be considered a girl at a glance” but you didn’t connect the dots yet.
I was scared of needles and injections once myself… but I had to get weekly shots for a couple years as a kid and for the first couple weeks I was very scared. But when you do it that often you  acclimate fairly quickly.
