Is there any scientific evidence that orgasm can be achieved by stimulating the prostate?
The 2023 article "Atlas of the Experience of Receptive Anal Sex in People with a Prostate" states:
While many debates exist regarding the existence and relationship of the “g spot” for men (most often associated with the prostate), there is no conclusive empirical evidence to suggest that the prostate is indeed responsible for these heightened sensations.
In the 2017 review "Prostate-induced orgasms: A concise review illustrated with a highly relevant case study" wrote (added to the question, but this review was already in the answer):
Because there have been no published laboratory-conducted investigations of the orgasms induced by prostate stimulation alone, information about them has to be gathered from the various websites dedicated to such orgasms. While unsatisfactory in that the vast number are obviously anecdotal they represent the only available source

In homosexual relations, most men do not reach orgasm in receptive anal intercourse, and a number report not reaching orgasm by any method in many of their sexual relationships, which they nevertheless enjoy.
Are there scientific studies with contrary conclusions?
