Am I Mastubating correctly???

Hi girls, I’m Gemma 33 yrs old and mother of two.

What I would like to know is am I masturbating correctly? From a really young age (like since I were a baby) I’ve been tensing my body and legs for around 6/10 mins, my mother took me to the doctors as she was worried I was fitting as I done this around 3 times a day everyday ! I never knew what this was as I thought I just done it to tire myself out when I was feeling relaxed or sleepy as a child.

Going into my adulthood I’ve still continued to do the same thing tense my whole body and legs everyday maybe 3 times a day, and I’ve found it’s a way of orgasm as I was told by the doctor. It’s a routine thing that I do in private, my thoughts became sexual around the age of 14, which added to the pleasure, I can take between 6/10 mins to orgasm, and my hand are no where near my clit or vagina.

Is this normal?

I don’t get stimulation from fingering myself and if I were to rub my clit it’s sensitive and pleasurable but I don’t orgasm, it gets a warm strange sensation but not as powerful as the weird masturbation I’ve always done! or will I if I keep going.

Does anyone else masturbate this way and why was I so young! How did my body know what to do from such a young age?
