Prostate orgasm?

I was having a sesssion today, after started on my front and getting some sensations and involuntaries, including a warm feeling on my prostate for a couple of minutes, i decided to take the advice of @slimjm on the following post

i lay on my back and maintained a contraction of my PC muscle (as if trying to stop urination) which brought on involuntaries that started to feel good. after a few minutes i had onset on pleasure in my prostate, lasting between 20-30 seconds where it felt like intense muscle contractions as if an orgasm. it wasn't quite on the pleasure scale of an ejaculation but as if i was getting a really intense handjob that was going to lead to an orgasm. the pleasure subsided

any thoughts?
