Had a look at Tantralink and they all seem legit. The male therapist would most probabely do the ladies extras, but have doubts about the ladies giving men extras?
I would be very surprised if you couldnt find at least a few of the 'Tantra' ladies from those sort of sites to go further (do research on ones you like and the kind of workshops they also put on or email them if you good with words/subtly lol) the impediment for me is it was cost a tonne of money and a couple of their sessions (to see if YMMV) or their often recommended 2-3 hour 1st connecty sessions will cost £300-£500 upwards.
I wonder because they pay such a lot for their training (I guess) on these courses etc, that they are then so money focused or worse, the course puts it in their head what they should be charging
They would rinse your wallet before they rinse you down
