Not this man!
These bidets/washlets take a lot of "seasoning." That is, seasoning of one's "bunghole." Trust me, I used them a lot when visiting Japan. You won't need "TP for your bunghole" a la Beavis, You need "diaper rash" cream to salve it. It gets incredibly sore, at first, with that water jet hitting it so hard.
Only after constant use for some time, does it get "easier" enough to develop a "tolerance" for them.
