Going on 11-12yrs here, I can't even remember exactly. Your hubby is blowing it way out of proportion. Once he's all healed up it's no big deal. 20min to change the appliance on a bad day. Being active is not an issue, and not having to worry about
where the nearest toilet is a godsend. Travel can be tricky depending where you want to go in the world, just bring double what you need and take it on carry-on. He'll be fine.
The hardest part will be diet, and figuring out how your body reacts to different foods. Some foods will give you liquid output forever, while some will give a solid sticky mess which is also no fun. Either of those make for zero-fun times. For me, a high fat diet seems to work very well, rice for a starch, and limited fruit and veg. Not to say I haven't eaten pizza and drank vodka til I passed out, ha. This op was the best thing that happened to me
