Yes, I would tend to lean that way. I believe we are coming from the same angle. Tantra or Tantrika's are terms tossed around very loosely. It is an advertising gimmick in my view. It is rather unfortunate because when you have the ability to spend time with one that is well versed on the topic, the experience can be very, very good. The issue as I see it, is that some advertise it, and are clueless when it comes to the true meaning of tantra or how it all works.
When a person is lucky enough to find a true highly skilled person with background in it (and they are like finding a diamond in the rough), or I often refer to them as a Tantra Goddess, they will provide experiences that are not typical at all. For example, a guy can feel like he is having an orgasm or something very similar several times during a 90 minute session with such a Goddess. Or he can ride the wave for unlimited amount of time. And never release so much as an ounce of semen outside of his body and be fully energized by it all.
