's porn career is off to a promising start -- TMZ has learned, Mystikal's #1 porn star crush has AGREED to have sex with him on film ... but he better not plan to get paid for it.
XXX star Pinky
-- who Mystikal named as his top choice to pop his porn cherry -- tells TMZ, she's flattered the rapper picked her ... and will gladly film a sex tape with him for her website.
But Pinky says she refuses to pay him -- because Mystikal is currently an "amateur" and Pinky doesn't pay amateurs ... "no matter how good he is in bed."
As we first reported, Mystikal says he's taking one last stab at the music biz before he gives up and turns to porn

This is not a joke. Mystikal tells us, he needs to make sure the money keeps coming in ... and if there's one thing he's good at, it's having filthy sex. So porn is his plan b.
Which is either crazy ... or perfect -- because Mystikal served SIX YEARS in prison for sexual battery beginning in 2004 after forcing his hairstylist to perform sex acts on him.
But Mystikal is undeterred, telling us he already has a history in porn -- winning an AVN award in 2003 for an adult movie he made (he doesn't actually have sex in it though).
We asked Mystikal who he'd want to star in his first skin flick, and the rapper said Pinky
-- adding, "She's a bad bitch. I would take her down in a second."
As for whether he's got the requisite hardware to be a male porn star, Mystikal wouldn't give an exact size, but said, "I'm definitely the man, the myth, and the legend."

The judge has already given Mystikal credit for 9 days served while he was detained following his February arrest. He has 81 days left.
