I asked my DH once what it was about thongs; I mean, guys have to know how weird they feel! (Before you're used to them.) He said it was that I was willing to wear them...
Anyway, as for the spice idea? Probably can't be of much help there. My husband and I are not spicey people- we're a rent a movie and make popcorn couple, on the rare nights we have together. We used to go out for dinner all the time- that can be fun, going to fancy places. But if you like the idea of a getaway, why can't you enjoy it even if you aren't getting away from anything in particular? Why not just a getaway from your own house and own bed??
I'd say plan a mini-vacation together. Or, go on hikes and pack a fancy picnic for yourselves and see what develops in the great outdoors...
