mental orgasm is a common thing to SB people???

I saw a post of someone saying that orgasm is all mental for us. I mean, it is like this for me, but I never thought it was something that most people with SB experienced??? What else about SB sexuality is something common to us? Since I've never had any sort of intercourse with someone, and also never talked to another person with SB about it, what I know about that part of my sexuality is only what I have experienced and tried with myself so far. I searched on the internet a few years ago to understand better how SB affected genitals and stuff, but I didn't find a lot of research about it. I'm a AFAB non-binary btw
