Fellow brown man here. Read my reviews, and improve your Japanese. I agree with
@TAG Manager, although don't read into it the wrong way; it really is more about the culture than it is the skin color. I am sort of an ABCD, so I get away with a lot more than my South Asian brothers. In regards to being barred, though, I have yet to be denied access to a place that white boys here managed to get into...but I am fluent in Japanese and seem to be pretty decent at appearing harmless so...
In regards to hygiene, shower, then get rid of excessive facial hair, brush, floss, gargle before you show up at the shop. Cut your damn nails till they are almost stubs, and sand them down smooth. Take a shower before going to play, and smile and be complicit when the girl washes you again and makes you brush your teeth and gargle again. Use whatever Japanese you can muster to ask her if she is okay every once in a while during the process, and please do NOT enact or even suggest any fetishes until you can ask for them clearly and understand the kinds of replies you would get from her regarding them in Japanese.
You need to be a saint...albeit a very, very horny saint...when you utilize these facilities.
You need to be the Francis Xavier of Facefucking.
The David Livingstone of Doggystyle.
The Mother Theresa of Missionary.
(I guess they were all missionaries...fuck my life.)
Just be a good kid and do us Desi kin proud. Then write a review on TAG and watch life get even better.
