I think we can all agree that if given the chance, we would all do unspeakable things to him involving flogs, whipped cream and a ball-gag. The only exception to this rule is apparently Gwyneth Paltrow, mostly because her heart is two sizes too small.

Gwyneth Paltrow and Robert Downey Jr. get to lock lips in the upcoming Iron Man 2, but Downey turned down the heat so things wouldn't get too "weird." 

He said: "She said to me that I didn't know what I was doing, like it didn't feel good. I'm like, 'You know what? First of all, we're all friends, so what would be creepy would be if I was coming off all sexy to you -- which by the way, I've done in movies and it creeps them out. So what am I going to creep you out for?' " (Source)

Considering that Gwyneth Paltrow has all the raw, unbridled sexuality of your grandmother's doily, I honestly couldn't care less. Seriously, if you want to recreate the experience of boning Gwyneth Paltrow, you can pretty much just slap some lipstick on a loaf of wonder bread and then spend two hours listening to it yammer on about how her "best friend" Richard Gere taught her about the importance of balancing your chakrahs.
