You havent had one! I love them. I go all the time

In fact, an apt once took me to a nice one . They give you robe and slipper well plastic ones,  
walk you to a sauna that smells like eucalyptus, a steam.
then they bring you to the assisted shower, body wash smells great. I asked what it is, its irish spring body wash, I use that at my spa now...actually.
its heavenly the whole being spoiled washed down, its relaxing.next they walk you back the massage room. you and friend lay next to one another, they give you bottle champagne. you can even hold hands as we did. it was very sweet.
xoxox you should experience it , it is great.
not an elderly affair at all. its so relaxing.

One of my BFFs from hobby land is from London, and I picked up her language lol. Hobbying abroad is a lot different than in the U.S. First off, very little screening is done because most are agency vs. indy, and the girls use flats vs. hotels. There are usually 4-8 women sharing these flats for a more brothel type feel, vs. women just sharing an incall, and leaving when one has a date. Rates are also a lot less, which is why I never made a habit of trying to make bank. I financed my trip, but that was about it. I've never came out ahead touring outside the U.S. but will say, it was worth it to see a few places.

That would be "A levels" which is in real life a reference as to what level of studies you've completed there in the UK. There is also "O levels"- which is oral.  

And "wanker" is technically a derogatory term for one who masturbates, not the penis itself. That would be the John Thomas.
