Woman With Two Vaginas on 'Strange Sex' (Video)

Season 2 premieres on TLC this Sunday.

The second season of Strange Sex premieres Sunday at 10 p.m. ET on TLC.

Watch a video of  Kelly, above, who learned she had two vaginas at age 15. "I didn't understand: is this a bad thing, is this an OK thing?" she says. "I was really scared to find out what else is different."

Her doctor compares her anatomy to a "double-barreled shotgun" and also explains that she has a "dominate vagina." Her second one is "about the size of a No. 2 pencil."
