Sensual massage studios in Stockholm are a bit of a hit and miss. Supposedly a one in five Asian parlor offers “extra services”. How do you know which ones? You don’t, but you’re more likely to find one outside of the city center. Remember that you’re actively committing a crime when you’re paying for a handjob. You could try Stockholm Erotic Massage (http://www.stockholmeroticmassage.com/), they offer outcall experience in your hotel room, but again there is no guarantee. Massage in one of the Thai studios doesn’t cost all that much, you can get an hour of decent relaxation for €40.
There is one sure way of getting a sensual massage in Stockholm, including a happy ending: escort directories. You can check girls who have profiles on these directory and classifieds sites since many advertise also massage services, be it on incall or outcall basis. Some girls in nightclubs in Stockholm also offer massage on the side.
