just out of curiousity, by "slept together" you meant "had sex," right? or did you literally mean, slept together in the same bed?
if youve already slept together and the idea of regular sex has been established, its not so bad to give her a gift. its one thing if youre giving a thoughtful gift to a girl youre ****ing; its another thing to constantly shower a girl with attention and gifts, hoping that one day she'll let you get a taste.
that being said, thoughtful is the ticket. something inexpensive and from the heart will go much further than an expensive, impersonal item. as an example, a while back i gave a gift to a girl id been seeing for a while. she always treated me with respect, cooked for me, bought me a pair of nice pants, bought me drinks, food, and just treated me like a king. the gift was not for her birthday or anything , either. no holiday. just a reward for her good behavior. it was something i thought of one day, and knew she would love it.
so what was the gift? a cd i burned, filled to the brim with our favorite love/slow songs. these were songs that we always happened to be listening to during our more intimate moments. songs that popped up on the radio, that we played on the jukebox at our favorite restaurant and others that each of us have personally enjoyed.
she loved it and if anything, it only increased her attraction.
