Dude if they’re close friends they definitely talked about your dick many times before so you shouldn’t worry too much.
As a fix maybe you can discuss this with your girl so she can clarify to her friends in some form that she’s getting plenty of dick despite the pic. Clearly she cares and seems like she’d go through with it. Just be open about it - your partner should be able to support you through this even if its silly, especially if its silly actually.
Maybe you wouldn’t be a bad poo poo brain your dad wouldn’t have left for cigarettes
