Obviously everyone is different, but my W told me she too enjoyed sex and had trouble initiating. Later I found out that many things she said may not totally accurate. Take it from someone that has dealt with this on an ongoing basis, be VERY careful and read the signs of her actual behavior - NOT her words. Your situation sounds all too familiar.
I realize you are seeking solutions and thus anything that sounds like it may work, has a positive glow to it. I am not a fan of scheduling sex...this can put even more pressure on the situation and if she is not into it, resentment will follow. I was not even into it during scheduled sex and I had a sex drive. Your mind will play games with you in that you think because it's scheduled, she is not into it...even if she is. Slippery slope.
