Was that "tantric masturbation"?

Okay, so after deciding to abstain from wanking for a few days, I then wanted to watch some porn. So I watched some, without masturbating, and then stumbled upon a video so sexy that my boner became really hard, the kind of hardness I can only usually achive through actually wanking. I concentrated a bit, really focusing on the video, and, I started to get feelings in my penis similar to when I have just masturbated slowly along my shaft only, but I was not touching my dick at all, and it was not rubbing against anything. I then started fantasising about sex scenarios, trying to really imagine the feel of it, and the feelings in my dick started to get more intense till it felt like I was about a third of the way to a really good orgasm. I also found that small movements such as wriggling my toes, squinting my eyes and flexing my hips intensified the sensations even more. Eventually they died down, but I then couldn't help but actually masturbate and I literally came within ten seconds, yet it was one of the most satisfying wanks i've had.

Anyway, I heard of this thing called tantric sex, where people can achieve orgasm through meditation, or something, and wondered if that's basically what happened to me.
