Be careful though not to overdo it. I went to Donki Hon the other day looking for gaijin size condoms, and saw the Okamoto horse size ("Super Big Boy" they are called). But next to those, they had a size with an elephant picture, called "Mega Big Boy"). OK, I thought, I am the big gaijin, so I went for those. Mistake! They are seriously loose for me. Absolutely meant for porn star performers and the like. Bit worrisome, actually.... So I will have to go back and get the horse size. I left one of the elephants on the hotel bed headboard, as kind of a privat joke. Poor J-guy who tries that...
In the event, if there is some elephant sized stud around here, I have a couple to give away.
