I guess you're right - both good and bad news on the loofah! Keeping that in mind, next June I'll ensure that if she pulls out a dark brown loofah, I'll casually suggest that she use that one on my unsuspecting friends in the next room...
What we do when we go to Philly is grab a couple of the weeklies (like NOW or Eye here) and flip to the back ten or so pages. There are tons of massage and escort places. There are quite a few that advertise the shower/table massages. I don't remember the names of the places we have gone to (usually too many beers) but they always seem to be either on Race or Arch St between N6th and N7th, just down from the Liberty Bell. The talent is hit and miss, but the quality of the massage and release are generally very good. I was offered F/S on the last trip (actually called boing-boing by this young girl who was slightly short on English skills) and took her up on it. Great time.
FYI, if you're looking for a good bar to hit on the weekend with a good mix of 20yr-40yr old ladies, Cavanaugh's on the water is a great place in the summer.
