Can anyone recommend a massage place in HK or Singapore that offers a full massage experience. Ideally bath, nuru, lingam, bj. Ideally want my cock worshipped for a couple of hours!

Check out www.go141.com  141 is HK's lingo for escorts.  Most are incalls that are mainly located in tiny apartments (there are these apt buildings with nothing but providers).  Sometimes they leave the doors open (with a closed sliding gate common in HK apartments) so that you can actually troll around until you see what you like.  Don't expect to find high-end providers.  On Hong Kong island, most of the girls are in Wan Chai.  There are also a lot of them in TST on the Kowloon side.  Some will do outcalls.

Not exactly what you describe, but the menu includes a shower, soapy massage and other good stuff. I was there a couple of years ago; it's a class establishment!
