officially scientists classify sex based on the size of the gametes the being produces. Basically if they produce eggs or sperm. The one with the larger gametes is female. I read this in a thing about female beetles with penises idk
This is also a good point. It is, after all, the whole reason sex exists (makin' babies.)
