anal vs prostate orgasm

Ive been having various orgasms using my helix for some time now and just would like to get other peoples views on anal vs prostate orgasm since im not sure which one is which. when i start within a few minutes start having some orgasms that peak and subside whic i assume is an anal orgasm. sometimes they are close together and blend making it a longer lasting orgasm so could be anal super o?

They feel like you are going to ejaculate then have a decay then another comes pretty quick.
Later maybe 40 min into session when i completely relax, no tension and fantasize another orgasm builds but is ill defined, doesnt seem to be localized to pelvis more whole body. Makes me writhe, beg, sometimes cry, have old emotional sex issues come up etc. very pleasurable and emotional. No real peak and decay of the other orgasms. so would that be the prostate orgasm
