I got the spark back in my relationship!

I have been dating a girl for about a year and two months and are relationship is great again. About two months ago I would'nt be able to say that. We just didn't have that spark any more. The sex life was transparent and there was no more intimacy. But I searched online for awhile and came across this ebook called love making tips and secrets. They have really helped me and my girlfriend get our relationship back on track. We always loved each other, just had a hard time expessing it, and this helped us out. I was just wondering if anyone else out their has had the same problems in their relationships? And if anyone has ever tried to read books on it?
