Josei Seven decided to investigate the charge of "sexless Japan" by convening a panel of foreigners to discuss sex in Japan. The group included two girls - a 27 year old Italian and 24 year old Canadian - and 3 men - a 37 year old Ghanaian, 36 year old Pakistani and 29 year old Romanian. I think FG member Screwed Down Hairdo might do this better justice but here's a rough translation:
Romanian - Japanese girls give great head. They're really professional. Best in the world.
Italian - Really? That's a surprise. I'm don't care for oral sex myself but my Japanese male friends always say the local girls are cold fish.
Romanian - No way! They might act shy but, when you get started, they really go to town.
Ghanaian - Japanese girls are good. Girls in Ghana don't do a lot but Japanese girls go all out for a full service.
Canadian - Well, Japanese guys ask too many questions when we're getting it on. It's all "Does it feel good?" "Do you want it in you?" "Where does it feel good?" Even afterwards you get "Did you come?"
Italian - Yeah, just shut up!
Canadian - It feels awkward not replying so you fake a few responses. "Ah, I'm coming!".
Josei Seven - You mean you fake orgasms?
Canadian - Sometimes. If he comes too early then it'll make him feel better.
Pakistani - Japanese girls might be acting up but they sure are screamers. I'm not too keen on that.
Ghanaian - Americans get pretty frisky too. Girls in Ghana hardly say a word. It's all missionary style and they doze off before you're finished.
Italian - Oh, we have a whole bunch of positions in Italy.
Canadian - In Canada, guys are more likely to give you a fingering these days and then you return the favour. Then you go full on after that.
