Orgasms !! 😩

Soooo I’ve never received an orgasm from a guy butttt I can always give them to myself. So I know very well when I’m gonna climax and when I am climaxing. My real question is how long are your orgasms typically supposed to last like mine only last about 5 or 6 seconds ?? Is this normal? Are orgasms supposed to be that short ? Or are they longer? It gets me mad bc they don’t last so long and I wish they were at least 30 seconds. But how long do yours usually last ????
