I think extra-marital sex is quite common in Japan. I had a years-long thing with a married woman and we were set up by our mutual female friend, who I think set up many of her married girlfriends with lovers.Yes am familiar how it works, makes me wonder as culture here in japan is different plus I don’t speak Japanese lol, as much as possible I want to be discreet and private. Question is where to find a nice and understanding SD. Thanks for the reply by the way.
