Me too. I'm 46 and my libido shot through the roof. And the more I had sex, the more I wanted it. It was almost a nuisance, really. Like I became so distracted throughout the day with thoughts of having intercourse or getting off.
I have read that for some women going through peri-menopause that this is very common (the lucky few!). For others, it's the opposite: no sex drive.
I hope I stay on the high side for a while. I know my husband is happier about that :-)
