Hello Welcome to HCM Your sugar levels are in normal range, there is nothing to worry. You have mentioned your hands and feet are cold most of the time. You are feeling low. Tremors are also present. First of all just to reassure you, Masturbation is a healthy practice. It has nothing to do with your symptomatology. Every adult male or female after attaining puberty masturbate. So it has nothing to do with your depressive symptoms. But continuous thinking about masturbation and beliefs about its effects are producing stress in you. It has increased the anxiety in you. Due to this you are feeling low and you are having tremors. You have mentioned that on seeing girls your semen just comes out. It is most likely not semen, it may be precum, which is lubricating fluid secreted on getting erection. I will advise you to divert your attention by reading good books, exercise daily, practice yoga daily. If problem increases visit a Psychiatrist for episodic control of anxiety. Medicines like Fluoxetine Paroxetine will not only cover depression, but will also help to delay ejeculation. Thanks Dr. Seikhoo Bishnoi
