It is suggested that you get thoroughly evaluated by your doctor. This is to ensure an underlying disease unassociated with diabetes is not causing your dysfunction. Then discuss with your doctor whether it is OK to take Viagra, or Cialis, or Goat Weed [aka horny goat weed]. The latter is not readily available, can be found [unsure about the UK] at some health food/herbal stores. Good luck
You're welcome. Glad to be of help.
Visit your endochronologist and have your testosterone levels evaluated. The test must be done early in the morning before breakfast. You may be prescribed transdermal testosterone. It comes in 2 mg/day and 4 mg/day patches. It is very expensive. And a very controlled drug. You place the patch on your forearm or leg every evening. Be careful not to use more than one patch a day. Unfortunately, it will not assist in obtaining an erection, however it will definitely increase libido and desire for opposite sex companionship. As an alternative, daily doses of DHEA will sometimes help, but you should have your levels tested before beginning this drug. All steroids can cause atrophy of the testicles and increase the probability of a malignancy.
