What makes you think males don't physically need orgasms for hormonal reasons?
You make a fair point! My post was somewhat jaded and geared at pointing out that with males, orgasms are not necessary for good
physical health... in general... The original post/poll doesn't specify 'in cases where a sub has emotional issues' or suffers from depression or any other specifics.
I was simply generalizing from a male chastity lockee perspective that I do not nor do I know of anyone, otherwise in good health, where 'overall health' has been at risk from being denied orgasms, for any length of time, but specifically 'long term' since this was what was being inquired about.
SO:
'are regular orgasms necessary for good health?' If otherwise healthy, no "BUT..."
'long term [greater than 6 months] orgasm denial is perfectly justifiable' No - "IF...." and Yes - "IF...."
There is no simple yes or no for 'every male', and for males vs females, completely different approach and answer.
In my experience, as a male, in perpetual chastity (going on 5 years now) and often 'denied' orgasm long term (rarely more than 4 months but often/most of the time around 3-4 months) where other aspects of health and well-being are in good shape (specifically, yet not specifically related to sexual wellness), my health does not suffer from being denied orgasms.
HOWEVER - my body goes through a 'healthy' goo purging cycle around once a week-10 days, then produces more, then purges.... I'm mentioning this, again, because if this doesn't happen, it's cause for concern, but in nearly 5 years, this hasn't been an issue.
Anyway... The OP encouraged a debate on the subject(s), so, this is my bit. I'm citing my own experience and opinion on the matter.
