Farrah Abraham's ready to raise the curtain on her rejuvenated vagina -- she's got a big debut in the world of online cam shows.

The teen mom/stripper/porn star/author landed a deal with CamSoda ... and will premiere on the site Wednesday evening. Farrah's no stranger to cameras in the bedroom, but this will be the first time she's doing it since her umm ... tune-up.

You'll recall 26-year-old Farrah had the surgery back in August.
