Can you have an orgasm without touching your sex?

at times it has happened where i get so worked up that i can have an orgasm with out anyone touching my penis. I had a massage about two months ago at a legit massage place and for some reason was so turned on with her massaging my legs while actually laying on my stomach. I started to feel the tingle happening below. I thought oh my god no, not now, but it just got so intense i just started coming right there on the table. I was so mortified I couldnt say anything to the massage therapist.

Only ONCE - a breast orgasm!
