I am hardcore on this issue. My parents *did* make out in the kitchen or whatever room they happened to be in. Not full-on groping, mind you, but full-contact embraces and lots of kissing; not pecks either. I wouldn't trade growing up in that environment for anything else in the world. I think adult physical affection between married people (as long as it doesn't get r-rated) is a *wonderful* thing to model for your kids. And the reasoning of people who feel otherwise really does escape me. It's not like you could ever isolate kids, *especially* teenagers, from all kinds of PDA and sexuality in the media -- why not send the messages that "married people do this stuff too" and "mom and dad love each other and aren't afraid to show it"?
