No I just gave you 2 pictures of Boz being erect and Mandingo being erect with the same woman. Here is the link with Spring Thomas and Boz. Boz only looks huge from certain angles and with petite performers. If Lex is 8.2 according to his dildo Boz would probably be under 8 inches. Unless we are going to be like the Manuel Ferrera wack job fans and say Lexington Steele's dildo is smaller than his actual size.

Here is a video with Boz and Shane Diesel in the same scene. Go to around the 12:00 mark. Boz looks to be the same length as Diesel with of course inferior girth. But lets say you want to believe he is slightly longer than Diesel. He still isn't 8.5 inches or even 8 inches.
