For me I'm not in the mood all the time, but consider myself about average 1-3 times a week, but if I'm not in the mood I'm willing to try and get in the mood with a little palying around but if I'm not after that then its a no go lets just chill and watch some TV or do something else together, I don't like to leave her alone right after I flat out say no to her but I leave that up to her.
