Oh I think there is a such thing as being too close, but I don't think you're anywhere near that line from what you described. I think it's wonderful and natural that you have such an affectionate relationship with your parents.

Some people have issues with things like this. While my mother's side of the family was very huggy, a kiss was a rare thing (unless dealing with a child of course) usually on the cheek. On my father's side of the family, they greeted you by giving you a kiss on the lips which made my mother uncomfortable.

I confess when my husband and I got married I found it odd that his cousin was 17 and came in and sat on her father's lap. But once I got to know them I realized there was nothing untoward about this situation, it was completely normal for them.

My own family is very affectionate, my kids still give me a hug and a kiss when they leave (whether friends are with them or not). We enjoy spending time together and I hope it remains that way forever.
