Squeezing pillows between legs, could it lead you to orgasm?

I've known sex since I was 9 (saw my parent's sex comics then I searched the internet then haha).. that was 11 years ago and that time i thought I got horny then in my room I tried to squeeze in my pillow real tight between my legs.. it felt good and felt my pussy twitching after... since then I've been doing it everytime I get horny.. I'm wondering if that pussy twitching can be called orgasm already? I tried to touch or finger myself just once and never really felt i orgasmed.. I've never had sex and I am wondering what do orgasm really feel like? Does anyone else do this squeezing pillows between legs?
