Former WWE star Tammy Sytch is being welcomed in the porn star sisterhood with open arms -- and other stuff -- because the sex game's biggest names say she comes pre-trained for sex-on-cam.
TMZ Sports broke the story ... Tammy, aka Sunny, is close to inking a six figure deal with Vivid Entertainment, and porn star Joanna Angel says she will fit right in -- "Porn is just like wrestling, it's sex on steroids, exaggerated. Wrestling is kinda like fighting on steroids ... it's the same thing."
For the record ... the WWE vehemently frowns on steroids.
That being said ... if Tammy wants to shoot a wrestling themed porn for her debut -- she'll have her pick of co-stars. Missy Martinez told us she's game to go a few rounds -- and Tanya Tate said, "She’s the first ever WWE Diva. I’d like to get pinned by her! Tag me in."
As for the big swinging male stars -- Nat Turner says what Tammy's really got going for her is ... "Dude's have been obsessed with her for years so she's already got the fan base. The more the merrier."
Like a Royal Rumble .. except that's not sweat on the mat.
