The 23-year-old actress is promising that she'll never do any nude scenes or be involved in a sex tape scandal.
"Ugh, never!," Fox tells 'MTV News'. "That's the last thing I want to see -- what I look like having sex."
"It would take one shot of me not looking good and I would not be able to have sex ever again, because I would always just see myself looking like a hippo having sex."
Fans also shouldn't hold their breath to see Megan Fox nude on screen, because she's afraid such a scene would live on even years later.
"I can't ever imagine myself doing nudity in a film," she says. "It lives forever, especially now, with the Internet. I just can't. I just can't."
Especially after Megan got a taste of the infamy when topless photos of her, wearing only skin-colored pasties, from the set of 'Jennifer's Body' leaked out last year.
"People take everything from you when you're in this business. Your anonymity is stripped from you," she laments. "They invade every part of your personal life, your relationships. Everything you say gets judged, everything you do gets judged."
"Literally all I have left are my private parts and I don't want to also share them with the world. I'd like to keep them private. That's why they're called that!"
