In the end, I hate to tell you this, ladies; sex is like everything else in your life, you are responsible to get what you want. The only person we can blame for not getting what we want is ourselves. Like any goal or dream, we only get what we're willing to ask and work for.
With the lack of sun and activity, our bodies slow down and go into a modified hibernation mode. Many develop Seasonal Affective Disorder (SAD) and need to take anti-depressants just to get through the winter season. Others find their creativity and motivation levels decrease. Still others actually LOVE this cold season and their activity levels, as well as their libido, go up. There is an increase in children born in late summer/fall as a result of all those people coupling in the winter whether to keep warm, to stave off boredom or as a result of being ridiculously horny!
