If you haven't changed your diet or lifestyle (exercise). And haven't started on the pill, vitamins or some medical treatment, the next probable cause would be thyroid problems or other hormonal imbalance, go see a doctor.

It just happens like that!  It's just our hormone level rises and falls at different times.  This happens to me a lot without my boyfriend touching me too.  I'll be minding my own business at work, then all of sudden, BOOM-I'm feeling horny as hell!  It's your hormones sweetie!  They rise and fall at different times!

It could be stress, hormone imbalance, medication she's taking, if she's older menopause, weight gain, weight loss, uterin condition such as fibroids....there could be a number of reasons. I work at a hospital, but you should ask a doctor or ask her why and recommend she see a doctor if she hasn't already.

a change in weather creates a difference in the hormonal secretion thereby affecting the mood.eg.in summer if the power goes off...the mind gets agitated.and in the winter u feel more sleepy.
