How much of life really concerns sex?

How much of life really, and truly, concerns sex (thinking about it, the act of it, etc.)? For me, sex is just one other aspect of life, yet when I hear statements such as Sex is the greatest gift human beings can give one another, I get quite alarmed....

My life has been concerned very little with it, and I tend to focus on everything unrelated to it. Have I been living in vein? Has everything that I've loved NOT for its sexual aspects REALLY its primary concern? Please answer ASAP!!!

I honestly don't think about it much. I have a lot of other things to deal with. I don't think people should treat sex like it's an everyday thing. I think it loses its value when it's done all the time. Then it's more like a chore. And no you are not living in vein =D Most guys can't get sex off their mind...lol.

Being a married mother of 3 small kids I really don't think about sex much. But when we do get to do it, it's wonderful. I think without it we wouldn't have the physical closeness that we do now. My husband is my best friend, he's everything I've ever wanted in a man but without sex we would be close but we wouldn't have any intimacy. Our lives are too busy to walk around holding hands (we're always holding a kids hand anyway), snuggle on the couch (a child always wants held) or even to go out for an evening together (finding a good babysitter is tough). So we get our intimacy from sex...so to us it's important.
