Hi Kimberly,
I'm not sure when the link between full lips and representatives of the adult film industry first arose, but when performed correctly, you should NOT look like anything other than yourself with fuller lips.
Megan Fox has indeed been blessed with full lips, and it is possible that she has had some additional help in that area. Given her rise to stardom, her sultry look appears to appeal to the masses, and I hear much more in the office about Ms. Fox's lips these days than Angelina Jolie's.
But you are correct: overly full lips look strange and unnatural, and should be avoided. If you stick with a hyaluronic acid gel (e.g. Restylane) or fat injections, and go to an experienced cosmetic provider who enjoys the art of lip enhancement and can explain what option may be best for you, you should be exquisitely pleased with your results!
