So, I've been with this girl like, 3 yearsish. And there aren't real problems or anything, but we both have noticed that the sex isn't as exciting/fulfilling anymore. We, of course, still have sex just about every time we're together -- many times a week, and often more than once a day. But it's becoming more like a habit to us. Has anyone had this problem and what did you do about it? I almost feel like we need to have sex less often but with more 'passion' if that makes sense. Any thoughts?
