According to your symptom (lack of sex drive), it seems that you might be experiencing frigidity. It doesn’t seem likely that frigidity is your greatest problem, however. The greatest health problem you might be experiencing right now is diabetes and overweight. Diabetes and overweight increase the risk for cardiovascular (heart attack) and cerebrovascular diseases (brain insult). Lack of sexual drive could be one consequence of these two serious conditions. Further, reproductive age has an impact on sexual drive. You can try to decrease your body mass and control blood sugar by asking for anti diabetic therapy. You can also check your blood pressure and blood fats at your GP's (general practitioner) office.
