Is a dick like that really exist?

Not really, it's inhumanly possible there are dicks that long just not that thick tbh they either have to be injected or are deformed or the dude has some sort of genetic defect that makes it where the soft tissue keeps growing but it became unusable essentially cus there's not enough blood pressure ╮(￣▽￣)╭ the bumps are probably implants aka pearls
