Any advices?

I bought a toy, it's an automatic thrusting dildo, my first time trying it and it felt nice. Although I am just not sure how to orgasm with it? I stopped in the middle as I was interrupted but I felt aroused and this ticklish feeling sensation. I feel like I am stopping myself from orgasming as to what they refer as squirting or I am just not familiar with the feeling? My main way of masturbating back then was thru humping pillows and I want to try something else, it feels different with fingering and using a toy, can someone enlighten me, please 💕
