FWIW, I would recommend seeking information through sex positive groups in your area, NOT working with the overpriced "tantric goddesses" advertising online with their nearly-naked assets on half-display in photos as they kneel in forest settings. They will try to charge you $300-$600 an hour for their "sacred" work, whether or not it actually has any permanent effect on your "kundalinic fires."
By attending gatherings for sex-positive people and talking with some who'd studied actual tantric massage, I was fortunate enough to meet an accomplished lady in her early 50s who was looking for a new student, and she definitely wasn't in it for the money. It was part of her life's work, and she really knew what she was doing.
My teacher had a systematic approach to training and she set high standards, but she worked with me patiently.
There's a lot more to tantra than better orgasms, and she could have just focused on the non-sexual aspects: especially since she wasn't requesting substantial monetary "offerings" from me. But she never neglected the sexual aspect. My teacher believed that sensual connection between provider and recipient (and being fully present with each touch) was an important part of the training; so we were both completely naked from the start to finish of each session.
And each session included sexual touch. Because her approach to tantric massage included offering multiple orgasms if the recipient desired them, my teacher offered to use her skills to bring me to a climax at the end of each session, whether coming was central to that particular lesson or not. (I happily took her up on it. At the beginning, climaxing me was done with her hands. She was extremely good at this, and brought me there with types of touching and areas of touching that were new experiences for me, as she did so. The climaxes were often full-body, very intense, and sometimes left me in tears.)
She told me at the outset of our work together that she and I might have intercourse later on, after my training was well along and if I wanted to learn tantric sex with her; but that most tantric massages don't involve intercourse or oral sex, so in the beginning, ours wouldn't, either.
I did pay her $50 for each hour of training, but even when a medical emergency with my daughter made that impossible, my teacher asked me to continue working with her, for free. It meant that much to her.
I wish you every success in finding such a gifted and dedicated teacher.
