I went to Senso (replied in another thread) but perhaps with more details here since this is about Senso.
Booked via Line and selected masseur before heading down. They are quite polite and responsive, even confirming that the rooms are already available for me before I arrived.
When I got there, one staff came to chit chat and asked if I've been before, or aware of the available courses. About 5-6 masseurs sitting around, some topless, some clothed.
I saw the masseur I pre-selected in the group.
Told the staff that I booked via Line, he double checked and then I was ushered up to the room (4th level) with ensuite bathroom.
Chose masseur who is lean/toned muscular who is totally my type.
He spoke decent English and was able to communicate throughout, making small talks. Showered before (alone) and after (together). Massage itself was good and proper, loosen up some of my knots... but lack sensual touches š
after turning around and facing up, he went straight into teasing and getting me excited for the extras, unprompted. Some licking, touching, sucking (quite surprised by this) and offered to get some action from the back.
After the happy moments, he was sweet enough to continue with massage on my shoulders, lower back while seated and commented on my body, made some small talks and showered together where we chatted further.
If I recall correctly, it was 1500baht + 1500baht tip for 90mins. Not the cheapest, but overall satisfied.
Tea and water offered before and after at the main waiting area too.
Hope this report helps!
