The Wikipedia extract includes "one third less likely to develop aggressive prostate cancer", so the importance is that by that and by other physiological effects that might exist and that OP is asking about, ejaculation frequency can affect life expectancy, and not dying is a terribly important topic. Probably far from the most cost-effective intervention, but worth discussion.

I think there no good reason to think that every ejaculation has the same effect.

Why do you think so?

If we're sharing anecdotes, I didn't ejaculate until a point in my early twenties after which I ejaculated daily. I noticed no side effects whatsoever.

Or we need a compelling reason why this topic is worth having a discussion over to the point where it overrides basic taboos. Signaling matters.

Reasons to downvote or dlslike this post as is that are either independent of or compounded by taboo concerns:

1) This could have easily been an open-thread question rather than a discussion post. 2) This only applies to half the population but that wasn't even addressed in the post. One is thus heavily implicitly assuming that all readers are male. 3) No apparent effort was made to find out anything else about the question before posting. 4) Unlike breaking some taboos, there was no attempt made to present an argument that this might be a taboo worth breaking. 5) The language used signals immaturity; "good fap" is not mature language. One can do a much better job breaking a taboo or getting people to tolerate it if one doesn't come across as immature. 6) You mentioned a Wikipedia article but didn't link to it other than to use a small, out of context quote where you didn't even give enough information to figure out what protective effects it was talking about. 7) You are a very low karma, relatively unknown user. We'd like to pretend we're good about looking for content more than who is posting, but realistically people are going to give substantially more benefit of the doubt to established users who they recognize as producing good content with decent ideas. 8) Implicitly assuming that ejaculation, orgasm and a satisfactory masturbatory experience are functionally identical (there are people here with significant others among other issues).
