It goes just like this: everything used to be fine in the sexual life of two partners and all of a sudden you realize that something has gone wrong. You don't get as excited as you used to at the beginning and you start to look for a reason in order to eliminate it. And the answer is as simple as it can get - your sexual life was simply too monotonous.

You used only one or two sex positions and have never thought about putting some more enthusiasm and imagination to your sexual life. The positions you were using were, probably, let's say, too classical and no wonder that you got used to making love in such a way and nothing of what you have been practicing till current was giving you real satisfaction. So what can one do here? Certainly, you can find a lover. And yes it'll make your sexual life more interesting for some time. But it's unfair to your current partner and who can guarantee that it is not going to become as vapid with the new partner? Of course, to come up with various love positions is easier said than done. But what  if you just cannot make up anything that would excite you? I think you should use a sex positions guide. You'll find many guides like that both online and in the book stores.

I am pretty certain you'll be able to find animated positions which will make your sexual life even more exciting than it has ever been. Simply talk to your partner and don't be afraid of discussing this subject. It's much better to discuss this awkward matter than to lose a person whom you really love.
