Well the situation is this, me and this girl, when we first started out, we were having sex almost everyday, getting intimate whenever we can. She was a virgin, but enjoyed sex so much that she initiated it alot of times, and would not say no if i initiate it. She had orgasms, no doubt about it... but after a few months, the frequency of us doing it gets lesser and lesser. she seemed to enjoy it less. Shes not so easily turned on anymore, she dont initiate it anymore. In the past, simple stuff like necking will turn her on, not anymore. Shes gotta be in the mood now. Her sensitive areas are not so sensitive anymore.
My question is, is this normal? a girl experiences sex, and subsequently loses interest in it. Is it because we did it too often initially?
Some background, we love each other, shes a nice girl, shes not screwing around behind my back, she thinks that a couple can go on forever without sex til marriage.
