I know a dude who told me how when he's hard he's anywhere from 7-9 inches long. When he's at his full hardness he's 9 inches obviously. I know he's not lying because I have seen him in all sizes of hardness. I've also met other guys who will grow half an inch when they are fully hard like go from 6.5" to 7.0" or 7.5" to 8.0", this was in person so I know they were not lying. Is this common? Is anyone here like this?
