Hi Caroline
My husband and I went to Phuket twice earlier this year and visited Soi Kepsap on a few occasions. We were looking for a place with attractive ladies from whom we could both get "happy endings", ideally together in a private room.
My guess is that most places will offer this service to ladies, though not all of the girls at each place do. The trick is to be a little up-front and make it clear before you go in, or before the massage starts, by asking if they will do a "sexy" massage. Otherwise, they seem reluctant to offer this service to ladies, perhaps in case they cause offense
If the girl you ask does not offer such services, invariably she will ask a friend of hers to help you out. Either way, you win.
There were two places of note, although unfortunately I can't remember the names. It certainly wasn't called "Bean Flickers", which I don't remember seeing anyway.
The best place is one of the last massage places on the left as you walk down towards the beach, just before the market stalls start. There are two places right next to each other, this one is the one nearer the beach. We originally chose it because the ladies sitting outside seem to be noticeably prettier overall than at the other places. I had a lady called Bee (I think), very attractive and willing !
On the same side, but further from the beach end is another place where most of the girls there are happy to lend a hand. I recall one lady called Son, lovely body though not the loveliest facially.
As I say, I can't remember the names of either place itself, although I may well do if anyone wants to throw names at me.
Hope this is helpful. Don't be shy and you will find exactly what you are after.
