How long have you been with your partner and has teh sex waned/dried up?

I've been with my girlfriend for 2 years. I'd maybe even say that our sex life is getting better. We sometimes have little conversations about sex..and one time I mentioned that (according toa site I go on) 1/3 of American women claim they have faked an orgasm more than once. She hand on heart said she'd never do that. and things like that make me feel so much closer to her...the more I fall in love with her the better the sex is. :)
