My estimate of top pornstars NBP x midshaft girth(when in good shape, add only 0.5 for BP) A slash represents the pornstar's in shape NBP or girth is between the 2 figures listed. Exact figures between quarter inches indicate extra info (reliable dildo info coupled with other factors.) If the pornstar is now out of shape, then their current NBP could be less by up to half an inch or even up to an inch in rare cases.
