If I've learned anything from Everybody Loves Raymond, it's that once you get married, sex is a highly infrequent occurrence -- something that requires a precise galactic alignment in order to take place.

Turns out, that old stereotype isn't even the worst of it. A survey, carried out by the British Heart Foundation, revealed that one in five married couples kiss less than once a week. Furthermore, when they do kiss, it lasts no more than five seconds for 40 percent of those couples.

Especially if you're young, this might seem peculiar. But when I think about it in the context of my parents kissing and my friends' parents kissing, it kind of makes sense -- although I don't know what goes on behind closed doors (and I'm okay with that). But as one commenter said:

"I am fifty plus, and the survey sounds about right to me. I get kissed twice a week."

But hey, that's not to say that just because you've been married for ages, you shouldn't try to ignite some romance. The survey shows that at least a small percentage of older couples are keeping the romance alive -- five percent of couples 45 and up kiss more than 30 times a week.

But is an infrequent kissing and/or sex life something couples should be concerned about? According to Susan Yager Berkowitz, an author on the topic, it simply depends on the couple:

"If a couple is content with intimacy less than once a month, and happily married, I doubt they would refer to themselves as having a sexless marriage."

But psychotherapist Tina Tessina, PhD, argues that a healthy amount of sex for couples is at least once a week.

"Intimacy keeps you glued together. It's what you need in order to nurture your connection to your spouse. You'll be a lot happier with each other and feel more cared about if you're regularly having sex."
