I have literally also just found this information on Christina's video which I know I will find useful.....

Music video

The music video drew controversy for its sexual content, including a scene with Aguilera in a bikini and chaps and spreading her legs in this shot.

The song's music video was directed by David LaChapelle. It depicts what was described as "a post-apocalyptic orgy".[18] The video opens with Aguilera gearing up and riding a motorcycle into a nightclub. Wearing a bikini and chaps, she is lowered from a cage into a boxing ring and dances, accompanied by several back-up dancers. A masked woman is lowered into the ring, and the two engage in foxy boxing. The scene is intercut with sequences of Aguilera dancing in a crop top, which she later removes to reveal a bikini top, and a microskirt. Redman then proceeds down a hallway, passing people such as mud wrestlers, a contortionist, and furries. The video proceeds to a scene of Aguilera and back-up dancers splashing and dancing while being sprayed with water in a room containing several urinals, as a possible reference to urolagnia.[19]
The music video was successful on video chart programs. It debuted on MTV's Total Request Live October 2, 2002 at number six.[20] It lasted forty-four days on the program,[20] half of which were at the top of the countdown.[21] At the 2003 MTV Video Music Awards, the video was nominated for Best Female Video, Best Dance Video, Best Pop Video, and Best Choreography.[22] The video lasted eight weeks on MuchMusic's Countdown, peaking at number eleven.[13]
The video generated some controversy and presented Aguilera's new public image. When Perry first saw the video, she asked Aguilera, "Are you high? This is annoying. Why are you doing this?"[23] Two weeks after its premiere, the video had already been spoofed by Buffy the Vampire Slayer star Sarah Michelle Gellar on Saturday Night Live, who said (playing Aguilera): "When people see this video, they gonna stop thinking of me as some blonde-haired, bubblegum, music-industry ho – and start thinking of me as an actual ho."[24] Aguilera later commented that it was disappointing and that she "could have made a funnier script out of it."[18] Protests occurred in Thailand over Thai-language posters in the video that translate to "Thailand's Sex Tourism" and "Young Underage Girls". LaChapelle stated that he had not known what the posters stated, and RCA disallowed Thai television stations from playing the video.[25]
Aguilera's new image was widely rejected by the public to the extent that it began to overshadow her music.[26] Entertainment Weekly described it as "the world's skeeziest reptile woman",[3] and The Village Voice captioned her as a xenomorph from the Alien series.[27] Several of Aguilera's contemporaries, such as Shakira and Jessica Simpson, disapproved of her image, finding it "a step too far".[18] Time magazine commented that "she appeared to have arrived on the set…direct from an intergalactic hooker convention", adding that "she earned that extra r."[26] Aguilera, stating that she like "to play and experiment, to be as tame or as outlandish as [she] happened to feel", stood by the music video and her image in response to the criticism:
When you are bold and open, artistically speaking, in music and in video, a whole bunch of people automatically feel threatened by you, especially in Middle America…OK, I may have been the naked-ass girl in the video, but if you look at it carefully, I'm also at the forefront. I'm not just some lame chick in a rap video; I'm in the power position, in complete command of everything and everybody around me. To be totally balls-out like that is, for me, the measure of a true artist.[18]
