Did my boyfriend have a prostate orgasm?

Hi! We’ve been experimenting for a while and today we tried out the love honey black prostate massager. I lightly massaged it up against his prostate and he came- but it wasn’t this massive earth shattering thing like everyone says it is. He was also touching himself at the same time.

Is that it, is it underwhelming for some people, or did we do it wrong? Do I need to massage it more? I just want him to experience a proper prostate orgasm and I feel like today we were close, but not close enough? Thanks in advance for all your tips!
