This might be TMI - and i'm totally serious - but in my case I suffer from severe bleeding if I do dry wipes. I purchase the "ultra-hard" (no flakes) variant of TP, dip about 1/4 of it into a cup of water, fold it in half, and then I wipe. Anywhere from 4-8 wipes, with the last wipe being a dry sheet to pat dry the area. This makes buying "standard" TP problematic for me, because that 1 sheet now turns into 2 or even 4 in order to prevent tearing up the TP during the wipe.
