My ex had a small penis and now I’m curious

What’s the most common dick size? My ex had a small dick, and the sex still felt good because a dick is a dick 😆 but I would have preferred a little more. I’ve heard the average penis size is about 5’ so I was wondering, in your experience, about how big are most dicks? I’m hoping that not all guys out there are my ex’s size. Weird question I know.
