Yes, diabetes can affect libido and sexual response. It does so by interfering with the body’s blood flow, including the blood flow to the sex organs; that can then affect arousal and lead to decreased vaginal lubrication. Additionally, if your blood sugar is not controlled, it can lead to poor nerve function, both in the genitals and elsewhere in the body. The best thing you can do for your sexual function is to keep your diabetes under control by managing your blood glucose levels. To combat vaginal dryness specifically, use water-soluble lubricants and spend plenty of time on foreplay before engaging in intercourse. Finally, be sure to talk to your partner about your concerns and communicate your needs. Although diabetes does create some unique issues in the bedroom, it need not prevent you from having a fulfilling, healthy sex life
