Olympic Sprinter Joshua Mance -- Porn Star Steps Up ... Forget Skin Diamond, I'll Totally BANG You

U.S. Olympian Joshua Mance's dream of bangin' a porn star could still be alive -- 'cause one of the hottest women in the flesh biz tells TMZ Sports she's willing to give him a shot at her gold medal.

We shot Josh a few weeks back, and the Olympic silver medalist made an impassioned plea for us to hook him up with porn star Skin Diamond -- which didn't exactly work out.

But sometimes when one door closes, another hole opens -- because Courtney Taylor tells us she saw our video of Joshua, and thinks ..."He is super cute. I'd be all about that boy."

Courtney -- star of "Art Of Anal 2" and "Interracial Swingers 1" -- says she's ready to introduce Josh to her style of banging, telling us ... "Trust me, he'd love his first porn star experience."

Ball's in your court, Josh ... until Courtney gets a hold of 'em.
