Brief Answer:
Circumcision.

Detailed Answer:
Hi.
Thanks for your small and very specific query.

It would be better if you can tell me a few more details, so that I am better able to help you:
Is blood sugar normal?
Does the foreskin tight since few weeks / months or since long ago?
Is it causing any problem in sexual activity / Masturbation?

I would advise you the following:
Get the blood sugar done.
If the foreskin is tight and not going back over the glans or causing pain or any other symptoms / unable to clean the underside, the most ideal treatment is circumcision.

Please stop applying betnovate locally.
You can apply liquid povidone iodine locally for cleaning.

I hope this helps you to take a proper decision and get a cure.
