CW: Genitals, transphobia
I once had a (former) friend tell me that he thought having a dick was what determined if you were a guy or not.
"I know plenty of girls with dicks," I pointed out.
"Oh, sure, a girl can have a dick. But it's *having one* that determines if you're a guy. You can't have a vagina and be a guy."
And intellectually I know he's wrong but sometimes I get inside my own head and think this way, and it makes me feel like I can't ever be a guy without one.
