Nick and Vanessa have had a rough few days after nude photos of them making out in a hot tub while vacationing in Mexico hit the press. While they were in the privacy of their exclusive resort, they were technically still in public, so it got me thinking about PDA. While it is nice to show the person you love affection, some people get very uncomfortable with public displays of affection. So how do you feel about this taboo topic? Do you think PDA is a good idea or bad idea?
