The non-sexual form can be based on admiration of the shape, size, or squirts of the other ‘s cock; the erotic form on mutual sexual activity, such as jerking off, cocksucking, or fucking.

Mark and Otis first experienced cockbonding on seeing each other’s hanging dick in the gym gang showers. They are now strongly cockbonded.
