I've answered this before, on an average, about 6 to 10 times a week. Is it outlandish to ask for sex, if I'm in the mood? Not at all. He knows me well enough most of the time to know when I'm horny (usually as soon as he walks in the door) but, if he misses my cues, I'll say something or just initiate.
Years ago, I rarely initiated. We had small children, and I was tired a LOT. So, I just waited until he wanted it. Before we had kids, I had a very healthy drive. Now that the kids are older, my time, especially in the evening and early morning is freed up, so I initiate a lot, as does he.
