I got a couple of PMs on places to go for overseas tantric massages. If there was one place that I would keep going back to, it would be the Temple of Bliss. They have centres located around several states in the US. The website is

I have tried both Luna and Maya for tantric bodywork and the experience with Luna especially was great. I had my best sessions there. I am not a fan but do give it a go if you are around the vicinity.
Another place that I have visited which is pretty good is WINKS London. You can find their website here:

I have also met another masseur recently who claims to practice tantric massage so I decided to try a 2 hour session. The whole session was quite disappointing but she did okay on the sensual tantric portion. I kinda like her touch and have decided to 'guide' her at my expense. I have booked in a 6 hour session with her to perform a proper tantric massage on her to show her what it is like. After which, I will get her to repeat the techniques on me. If she turns out to be much better after some guidance, I will have another contact to share with everyone here.
Enjoy my friends but respect the masseurs/ therapist!
