This is just one anecdote, but I'd like to share my personal experience. Fitting in with the typical boys who took computer classes in high school was really difficult and unpleasant. I'd been using computers and writing code longer than anyone there thanks to parental encouragement, but as a girl that didn't matter.
Girls in the class got picked on all the time. I got nicknamed "secretary" and singled out every class by the other nerds, getting told to go be a secretary because I could type fast, should input their code for them instead of writing my own, etc etc. People pulled classic bully moves like pulling my chair away when I went to sit down. I felt more bullied by them than I ever did by other kids. In my personal experience, the socially awkward computer boys were actively unwelcoming to girls, and awkwardness did not preclude meanness.
