Romance is not just the candles and the dinners and the dancing in the living room. Romance is also the little things that she notices you have done for her. My favorite kind of romance is the change-up. Just when she thinks "awww, that is so sweet," she finds out that there is more to come; and then more, etc. This is subtle and simple, but it makes her take pause to appreciate you. It is subtle romance that when intermingled with the big surprises and the nice things you do every day that will really make her see that you love her – she will feel it deep inside and then her libido will get that spark it needs. What you want is for her to think of you in the middle of the day and smile – that kind of feeling is priceless to her.
Here is an idea you can use to give her 10 days of romance for about $15.00. Go out and buy 5 bottles of fragrant hand soap for your (and her) bathroom (about $3.00 each on sale). Seriously: soap. I got mine at Bath and Body works. I test smelled each bottle in the store and chose the ones with the most romantic smells. For example: the cucumber version smelled like a salad – not so good – but the cucumber melon version smelled really fruity and fresh – a winner. Here is what I settled on: Cucumber Melon, Sensual Amber, Brown Sugar and Fig, Tropical Passionfruit and Country Apple.
Next, just replace your boring hand/face soap with one of the new scented soaps. Hide the other four. Don't say anything. The next morning, she'll most likely notice the new scent. And she'll probably say something like "wow, this smells good – that was nice, hunny." The next day she'll notice again. But by the third day, it will be "the norm" – she'll be used to it. So don't let her get used to it. Switch the current scent with once of the hidden scents and hide the first one. Don't say a word.
She'll notice again. "Wow, this is really nice smelling." Two days after: move to the next scent. She'll notice again. By now she may have caught on to what you're doing. My wife kept going for about 3 switches before she realized why each day the soap smelled so good and she never got used to it. We had a good laugh about it. And she thought it was really nice. So – I keep switching every now and then and she notices – but she doesn't always say something. That's cool, though. I know she appreciates it. 
NOTE: if you use the same soap I did (Bath and Body Works anti-bacterial hand soap), do NOT use it as a body soap in the shower. It is best for just your hands and face. If you use it in the shower, the anti-bacterial properties will upset the balance of skin surface bacteria in places like your arm-pits and groin. And you will actually start to stink – bad. Just hands and face. There ARE body shower soaps you can do this with, by the way – and it's equally effective – if she likes showering with scented soaps.
