Wanna have a casual fling with "Blurred Lines" super babe Emily Ratakjowski? Sounds like you can! Now you too can get in on the action every dude in America (and beyond) wants in on. The Gone Girl star just set every noncommittal man's heart afire when she said she's into casual flings.

The proudly big-boobed actress just told Cosmopolitan magazine, "If I want to have casual sex, I'll do it." Umm with a body like that -- we can't imagine that would be a big problem for you, Ems!

The casual sex fan also added, "I feel lucky that I can wear what I want, sleep with who I want, and dance how I want, and still be a feminist."

The brunette also commented on what it was like to be intimate with famous costar Ben Affleck: "The whole experience was a little surreal."

We've heard infidelity rumors about Affleck for years -- so we gotta wonder if Ratakjowski used her bedroom eyes and her free-love lifestyle to lure the the big, buff actor into a no-strings-attached romp ...?
