Sorry if this is offensive, vulgar, or superficial.

I didn't realize how much I cared about dick size until I actually slept with a guy who had a gigantic cock. He was overwhelming both in length and girth. There was nothing about his other features that would have made me think he had a big dick other than that he was 6'4", but I don't think this is reliable because I dated a guy who was 6'6" and he had a bit of a pencil dick.

I don't know exactly how big he was but I'm fairly certain he was a statistical anomaly. I think this trait is really attractive and it'd be even better if a guy I liked before seeing naked turned out to be hung. So how would I actually find them short of specifying it in a dating app? Do you just date multiple guys and find out and pick? Is there some sort of BDE you can pick up on?
