Yes, there are MEDICATIONS to decrease sexual arousal. These medications are called anti-androgens. They work by blocking the effects of testosterone and reducing libido. But without discussing your other hhealth issues it is not possible to prescribe any medicine here as these medications can have side effects and may not be appropriate for everyone.

You face a challe­nge with erection difficultie­s due to diabetes. High blood sugar le­vels harm blood vessels and ne­rves.

It's vital to be aware of the fact that feelings of attraction may come up, but when they get too intense, they may indicate a root emotional problem. This might stem from the lack of needs being met to patterns of attachment. Recognition of these emotions is the most important thing. I would suggest you to consider turning to a mental health professional who will be able to help you and also provide a secure place for you to openly express your feelings. Through this process, they will aid you in the examination of these emotions, and assist you in developing more adaptive strategies for coping. However, just remember, when you seek for assistance and you share your problems, you actually take the first step toward knowing who you really are and the right way to deal with them. Your well-being is the priority, and professional counseling will help you navigate it.
