Fissures can hurt a lot.
Here (Brazil), most toilets have a little shower just besides our "sitting" place". It cleans all out and I just have to dry the area.
In portuguese is "ducha higiênica" something like higienic shower? You can google it... and meybe have it installed for you.
When I travel to US I find it hery hard to lean just in wet wipes.
good luck...
