A J-poucher that we got a lot of preliminary info from (he has had his for 23 years) uses Desitin. As it turns out hubby ended up with the permanent ileostomy but that is what he would have been trying.
Using wipes as suggested also. There are flushable ones you can also buy.
Not everyone can or wants to have a bidet or have their toilets outfitted with a special set up to wash and dry the rear area but if it is affordable and possible, pouchers who have them have raved about them.
The barrier cream is needed to be used each time to keep you comfortable from what we were told too.
