A reader suggested,
"I think a great holiday gift for a spouse would be a fulfilled fantasy. You could wrap an empty box and when they open it, tell them they get to choose the fantasy that you will fulfill. If you are nervous that they will choose something that you aren't ready for then perhaps you could make a little coupon book of the ones you are ready for."
I LOVE this idea! Fulfilling fantasies is a great way to add a little variety, increase closeness and have some fun. You can get some ideas here and here. If you need costumes, lingerie or toys try here and here.
What other hot ideas do you have?
