The reason men's moods change after ejaculating is because of the brain releasing a slew of endorphins and neurotransmitters which include dopamine the feel good neurotransmitter.
Most men's mood does change after ejaculating and some men after ejaculating feel relaxed and may even fall asleep afterwards.
And other men who ejaculate feel inspired and read to work on other tasks and some men just feel the same or feel the release of tension and be in a better mood after ejaculating.
If a man goes a year without ejaculating the sperm that is unreleased will break down and then absorb back into the body.
Not releasing sperm or going a year or longer without ejaculating will not cause any health problems or harm.
There's no age that a man stops ejaculating although some men will stop ejaculating when they are between 55 to 60 years of age and others may continue to ejaculate until they are 70 or above.
It's still possible for men to produce sperm and ejaculate even when they are past 55 to 60 as it can depend on the man.
Men typically never stop producing sperm, but there is a measurable decline in sperm quality as a man ages.
The World Health Organization (WHO) has a set of benchmarks, known as semen parameters, for healthy sperm, including count, morphology (shape), and motility (movement).
With advancing years the amount of capsular tissue increases in the mans testis.
A man can cum as often as they want to per day.
Some men cum as often as 4 times to 8 times a day and some men cum some more and others less.
A man releases sperm between 15 to 21 times in a week.
However there is no normal amount of times that a man should release sperm in a week or month etc.
It's all dependent on the man and some men don't release any sperm at all in a week or even months.
It's okay and normal to not release any sperm or ejaculate at all if the man does not want too at that time.
Myself I can go months without releasing any sperm and I'm fine.
If a person does not ejaculate, the unreleased sperm breaks down and absorbs back into the body.
Not releasing sperm should not cause any health problems.
However, if a person tries to ejaculate and is unable to, this could be a sign of an underlying medical condition.
Practicing semen retention is thought to boost testosterone levels, improve fertility, and lead to more intense orgasms.
It is hard to say whether there may be any real benefits of not ejaculating (medically referred to as semen retention).
There is not enough scientific evidence to recommend this practice to all men.
The body reabsorbs sperm that does not leave through ejaculation.
This has no side effects on sex drive or fertility.
However, there may be possible side effects in people who delay or avoid ejaculating when sexually aroused.
Epididymal hypertension is when male sexual arousal does not result in orgasm or ejaculation.
