Taylor Swift -- I'm the Poster Child for Slut Shaming (VIDEO)

Taylor Swift's been publicly tagged as a chick who sleeps around with guy after guy after guy -- at least that's how Taylor sees it, and she's pissed about the rep.

Taylor did a 73 questions thing with Vogue, and one of the scripted queries was ... "What's the one thing you wish you knew at 19?"

26-year-old Swift took a deep breath and replied, "You're gonna date just like a normal 20-something should be allowed to, but you're going to be a national lightning rod for slut shaming."

You have to see the look on her face too ... she's not joking (it's at the 8:00 mark).

Even though her list of ex-BFs -- and songs about those exes -- is impressive ... we can't recall anyone calling T-Swizzle a slut. But it's clear she's taken all the talk about her love life to heart.
