Well after spending much time reading this thread, I decided to give it a go.
I popped in to Thai Oriental Spa in Leamington. It's down a very quiet street, no over looking houses, so I felt very comfortable.
Went inside and to my surprise there was a English guy behind the counter, about 50 years old, I'm guessing the owner, but very friendly. Very tidy and clean.
Opted for the £35 for a hour. He called down the girl called Amy, quite a nice looking girl, a bit bigger built than your average thai girl, but no problems there as I prefer curves.
Her English wasn't brilliant, but could communicate, as it was my first time I was unsure how it all worked, so I just stripped off at the request of Amy. No mention of any extras at the time. She started massaging me , and after about 15 mins she asked if I like Thai Massage, then she said 'everywhere' , so obviously I said yes and she said we can talk later about it.
So after a while she turned me over and her hand went straight to my cock, and said £20 for HR and £60 for naked. Opted for HR as the naked one seemed very steep! But she did strip down to lingerie for this.
Overall massage was excellent, relaxing, and very firm, also she stretched and pummelled me a little too.
Well recommended and I'm sure if I was a bit more experienced I could of haggled with the prices of extras.
