Maybe I've learned a thing or two about getting widebands off. I swore off of them last time I used one, too.
If you're to the removal stage this advice is mood. But...... trim johnston of any and all hair lest you sound like an Indian on the war path when removing........
Use a hot washcloth, it softens the "glue" do this two, three, four times getting all areas as hot as you can stand.
Slowly peel the thing off bottom up. If it's grabbing some of that sensitive skin ( and believe me, it's all sensitive ) get some TP and soak with alcohol. Apply the alcohol pad you just made to the interface where the condom is pulling the skin. Alcohol will "melt" the glue, but go slow pulling the condom gently while applying the rubbing alcohol pad where the cath is bonded to the skin. Remember you don't have to remove it all at that moment (assuming someone isn't waiting for you) so if things are difficult you can always walk away then come back for more removal. I also use a pair of scissors (gulp) to cut the excess catheter as I'm removing it. Just don't cut yourself or cut so much of the cath off that you can't get hold of it.
Just be patient and it will come off. Don't hurt yourself! When it's being really difficult slow down and use more hot water on a wash cloth, then the alcohol again.
