Not sure that you will need a rubber ring, your belly will hurt most. Dunelm do a waterproof sheet that doesn’t feel like rubber; alternatively, you could buy some disposable puppy training pads from any good pet shop. Other shopping list suggestions:-
- a bucket to stand the night bag in
- underpants (not boxer shorts) in a size larger than you usually wear
- tracksuit bottoms in a soft material and dark colour; ideally with a drawstring waist rather than elasticated (M&S did sell some in sweatshirt material - not sure if they still do?)
- clarify whether the hospital will provide local anaesthetic such as instagell for the eye of your penis; if not, buy a tube
- a few (not hundreds yet) incontinence pads such as Tena for men or Boots own brand for men (also check whether they are provided on the NHS in your Trust
- books / puzzles
Assuming you are still having non nerve sparing, ask now about whether there is an ED service or andrology clinic in your area and whether it is the surgeon or GP that will need to refer you. The earlier the referral is in, the quicker you are likely to start on penile rehabilitation afterwards. Also, between now and the 29th October, you may as well start doing your pelvic floor exercises to get the technique right.
