I'm getting so old - it's more uncomfortable to do those scenes now than when I was 20. I mean, I don't have a big problem with nudity on screen. But usually the days when you do those naked love scenes are the weirdest ones on set. Everyone is uncomfortable. You're like, 'Hi. How are you?' Then the next minute you're with an actress who you don't know and you're pretending to make love to her in front of all the crew. The acting challenge is pretending things are OK.
