Sorry, I did not see your post here through the holidays.
If we base love on our feelings (emotions), our emotions often fail us. Unfortunately, too many marriages fail based on feelings rather than making a daily choice to love. Love is a verb (actually I think there's a book by Gary Chapman with that title.)
Those little "skip a heartbeat" moments come and go over a lifetime of marriage. When you can look across a room and say to yourself, "That man is still mine," means a lot. Or, whatever the moment - a smile or a touch and your heart skips a beat. For many couples, this takes effort to remember to do things together that create fun. Fun is what brought you together, and it's what will keep you together.
I am in a place of comfort and deep satisfaction in my marriage. The knock your socks off moments still show up from time to time (makes you appreciate them more), but not like when we first married. To be honest, I wouldn't want to go back to that place - we've grown too much with God as our guide. While things were defintely more heated in the bedroom (being 19 & 20 helped), things were also more heated when it came to communication and conflict.
Fondness is a great thing, but I would be concerned about controlled affection. What does controlled affection look and feel like?
