I don't know but to me there is no way he is at the same lengths as someone like Jax Slayher.He looks bigger than 7 to me. Definitely not 8 but I could believe anywhere from 7.25 to 7.75 for him.
I mean look at the two attachments between Keiran Lee and Dwayne. Keiran Lee is 7-7.25 and Dwayne looks around the same length as him except Dwayne is obviously thicker. I can believe 7.25 but no way he could be more than that. I know more girthy dicks make the length look smaller but it's not by that big of a margin.
