I find this thread very interesting, mostly because in my circle of friends, it is usually the women who are complaining about a lack of affection, not the men.
It took me a long time, but once I figured out that men and women are wired very differently emotionally, things drastically improved in our marriage.
Are you sure that there isn't something bothering her and she is taking it out on you the only way she knows how? I have found that it is rarely about one issue, it is one person shutting down because of something else going on. Women sometimes find ways of punishing men that make no sense to anyone but them.
What works for my husband and I is to go out of our way to spend as much alone time together as possible. Our children are 11, 14, and 18 so it is a little easier for us. Even if we can't get out of the house, we will watch a movie in our room, or hang out in the basement, or cook dinner together. We talk about our day, and we really LISTEN to what the other person is saying. That is harder than it seems because sometimes he talks about work which is less than interesting to me. We have decided to make each other our top priority, even above our children, which I know a lot of people disagree with.
I think in order to have physical intimacy, you need emotional intimacy first. have you ever tried emailing her during the day just to say hi and that you are thinking about her? My husband and I do this all the time. Most of the time the emails are g-rated, but it is fun to send an R or even x-rated email to each other once in a while. Once you regain that emotional closeness, the physical affection often follows.
I do feel for you though. I have a male friend that is trapped in a totally affectionless marriage and it is devastating to him. I never realized how hard it was for men until he told me about his situation.
Good luck, and I hope things improve. I think the fact that you are looking for advice is a good sign.

Personally, I won't hold affection from my DH in front of our children. I don't want them to see a copy of the honeymoon night, don't get me wrong, but it's important to show that marriages DO stay together in a positive way, not "just for the children," and especially in a world where what they're learning about the birds and bees WAY early, and in inappropriate ways. You want to show them positive affection. I don't see the problem kissing in front of children, but really- what's going on with her is something deeper.
