Not my thing, except for my urologist, and even there, RELUNCTANTLY. Besides Analisa, you might also consider Paradise, soi 22. But been awhile ago.

You might also consider the (in)famous Tulip, Thong Lor BTS, Sukhumvit/Soi 55, on the right hand side heading away from Nana, basically underneath the station. Ladies certainly have toys you can use on them, wouldn't surprise me if they'd return the "favor". On ISG (yes, homework), Tulip has its own thread.

And if you're up along Soi 55, Misaki Akasuri (previously Known as Sakura Asuri) for "salt tapping". Don't worry, they're not going to pound salt up your ass. Certainly a happy ending, maybe bodyslide, but you will never feel cleaner (that's the "outer" you, not the "inner"). Korean thing. Always a must stop for me.
