Best of luck to you brother, and looking at my reply to you, I apologize now for being a dick. Just getting frustrated with clueless newbies, but I see now that you’re trying to find a way to get comfortable here so yeah…I will be more respectful to you now.
With that, another real piece of advice for you:
If you can get your foot in the door, pay for sex. It is so much easier to see how the game works and develop a relationship with Japanese women when you get the post nut clarity in the willing loins of a provider. Nobody judges you for it here…well at least if you keep it to yourself…😂
Before that, I suggest earnestly taking up learning Japanese. Despite what people say, learning the Japanese language is about persistence, not about being smart, scholastic, or resourceful. If you can at least carry on a conversation, your sex life here will massively improve.
