I don't know about Korea and Japan ( I have travellled to both countries but don't intimately know the people)
I do know that Indonesia (which has a major Chinese influence on the people through trade going back like 2000 yrs.)
Nearby Malaysia also, and Phillipines I have heard.
You are a spinster after 30!!!!
It is bizarre man, a lot of these women remain virgins in hope they have some valuable marital qualities, I do not joke this is for real man.
If you are a divorced woman aged say 31 and you move back to mom and dads place in Bali or some town near Surabaya then you are a known non virgin and the women around know you are on the prowl for a man THEY WILL HATE YOU AND WATCH YOU AND SLANDER YOU)
Rural Korea and Japan are probably the same way.
IF YOU ARE NOT A VIRGIN YOU ARE NOT A DECENT WIFE
Catholics are similar and these women will suck cock, let him eat her out and do ALL THE BUSNIESS...NAUGHTY SHIT BUT HE DOES NOT STICK HIS DICK IN HER PUSSY.
They are very prim and proper but when they get naked and hop in the sack they are awesome
One thing the woman will do when they are "playing" is let the guy slide his dick on her pussy like he is fucking her in that motion. BUT NO PENETRATION
I have done this stuff and it is as good as if you fucked her
no baby worries
and she massages you, sucks your cock, you can eat her out or 69 her (mmmmmm) let put her on her back like your gonna fuck her
Shes slippery wet. and slide your dick over her clit and watch her cum
Shoot it on her tits
Good times, Good times
