too funny... as I had a recent experience. i was a banking assignment that pretty much was in Chinatown San Francisco... it's filled with legit foot massage, accupuncture, beauty salons w/ massage, etc.... VERY well priced, but you just don't know.
turns out there's a few "massage/escort/hooker" review sites. a big one in SF (one that local authorities used to bust a few places, however the chinese underground crime ring, pretty much has everyone paid off) is
San Francisco Bay Area Escort, Massage Parlor Guide : myredbook . you may have one in your area.
basically, I guess a place with a shower, and/or late hours ... you can go pretty far. i've never (and never will) had a hooker, but was intrigued with the concept of happy ending. I went for a massage at 11AM... and enough hints were thrown around.
after the massage, I flipped over said thanks, and she said something along the lines of "you want massage anywhere else"? touching my chest, then hips, and I thought "fuck it, I'll trip this bird out [and she was pretty cute, just English was piss-poor] with a nice monster load". then she touched my crotch. I said sure, and asked the price. $40... done. she did start laughing when I came, but it was a kick shooting across the bed, against the wall, etc... not sure i'll do it again, but was a fun experience. i guess while you are getting your massage, you can just ask about services they provide, a la different massage type/time periods. that might be a hint.
