yes. you're probably right. for most women, the biggest turn on after a few years of marriage is to see your husband doing the dishes or listening to you talk without yawning or nodding with a blank stare. oh, and start in the morning. like get up and bring your wife breakfast. you know, tea and scones on a tray. then, say something like, i know it's not our anniversary, and you may think that i want something, but really i just love you and want to spend the whole day with you. tell her you want to go to the mall with her. and, maybe catch a romantic movie. maybe, if she likes music, a concert or museaum.
women often save grudes, too, so you want to get them out of the way. for instance, if there is a job around the house that you have been putting off for several months, years...just suddenly proclaim an interest in it. you don't even have to finish the job totally, just look interested or busy in the general area.
learn to dance (this one's for my hubby) and surprise her by knowing a few steps (other than the usual square). buy her something (jewelry or lingerie), bring home chocolate or flowers. just some ideas. oh, i forgot poetry. maybe write a poem for her?
