Recently, I got hooked by tictoc, watching some clips for hours while going by train. Videos on hashtag #mascgirl made me reconsider if I was a (fem)boy.

Short answer: No.

Long answer: If being boy was strictly only about having a penis (or testicles or penis and testicles), then it was an easy yes (except for the question how long a penis had to be to be considered a penis ...). But, if it was just about having a penis, why calling it something so confusing then? Why not...
