Had a conversation tonight where this popped into my head, so I figured I'd go ahead and put it up.
When your significant other gets home, surprise her with the bed covered in rose petals (or whatever flower she likes; rose petals are just big and soft and somewhat resilient. If you get tea roses, they'll even smell nice). Help her take her clothes off, brush her hair (preferably with a natural bristle brush), and lay her down on the bed. Give her a full body massage, with nice smelling lotion or oil (unless she doesn't like that kind of thing), making sure not to concentrate exclusively on erogenous zones. Then fluff the clean sheet over her, tuck her in, and put her to sleep. (A nice added touch - read to her, or sing to her, or if you can play an instrument - something soothing.)
Unless she initiates sex, don't do it! I have to tell you guys something: I've not yet met a woman who didn't have this thought go through their head at least once, even if subconsciously: "You're just doing this so you can get laid." If you can do something this intense without managing to jump her, then if she doesn't realize how much you care about her, she's a moron.
BTW, some women might be so insecure that they think you NOT jumping them means you don't find them attractive or something. Take them to a counselor.
