Sex Is Good For You
It is interesting because science has discovered, mostly in the last decade,
literally a dozen major ways that sex is good for you. I want to go into
here three of the most important for us guys.
This is critical to understand, because there are guys who have become
discouraged with relationship(s), are depressed, have given into erectile
dysfunction and other things to where they have turned themselves into a modern
day monk without sexual activity. I am going to show below that
without sex is dangerous.
You are literally wired from puberty on and the ground up for a lifetime of
sexual activity. By the way, I emphasize a
lifetime of sexual activity
because that's one of the things Peak Testosterone is all about: giving
you the tools you need in order to stay healthy, fit, full of energy
Below is what one might call the Big Three List of the just what the studies show
sex does for men. I would argue
Sex is on an equal, or very nearly equal,
footing with diet, exercise and sleep with regards to your health.

great reasons to spend more time in the bedroom.

1) Sex Raises Testosterone. I discuss this at length in this link about
How Sex Increases Testosterone. One of the reasons for
this is explains why sexual intercourse is so much more satifsying than
masturbation. The reason? Simple - four times as much prolactin
is released after intercourse.  And this applies, perhaps counterintuitively,
to both males and females. Prolactin is associated with sleep, which is likely
one of the reasons we sleep so soundly after intercourse, and sleep is one
of the Best Natural Ways to Increase Testosterone. In
addition, prolactin itself may increase testosterone levels to a certain extent
as well. 
Another reason is likely the chemical soup released during orgasm, including
vasopressin, prolactin and dopamine may stimulate testosterone in ways that we
do not understand yet. We already know how much
Testosterone, for example.
2) Sex Boosts Erectile Strength. This is due to a variety of factors
including exercising the pelvic muscles, boosting neurotransmitters, lowering
stress, improving sleep,, increasing testosterone and much, much more.

3) Sex Is Associated with Less Heart Disease and Other Cause Mortality.
1997 Welsh study found a 50% reduction in mortality for guys with the most
orgasms versus the guys with the least.  Furthermore, the relationship was
dose-dependent, i.e. the more orgasms the more protection - an indication of a
true correlation. Mortality studies are extremely important and considered by
many the "Gold Standard" for health. After all, extending our life span is
certainly one of the most important things we can seek after in fitness and
health. Dr. Oz, of Oprah fame, looked at this study and recommended guys have
around 200 orgasms per year. After hearing that suggestion, he's the
Wizard in my book...
4) Sex Improves Blood Pressure Response.
That's right - researchers found that penile-vaginal intercourse (PVI) improved
stress reactivity, i.e. arterial blood pressure response to stress.  And you thought research was dry and boring? Now it's important to
not that only PVI and not other sexual activity had this effect. I have already
written to the department chair asking if they need volunteers for any follow-up
5) Sex Increases Sensitivity. Oxytocin is released from touch, as
I cover here, and a nice burst during orgasms in
both men and women. It is known as the "love hormone" because it creates
feelings of bonding, intimacy and empathy. And
let's face it: most of us guys could use a good dose of all three.
6) Sex Reduces the Risk of Prostate Cancer. In one study men who ejaculated over
21 times per month had a significantly reduced risk of prostate cancer.
 As a
side note, we know that sex raises testosterone so notice that this implies both
sex AND testosterone are good for the prostate. (Yes, it could be stress
reduction and other factors, but this ties in with the fact that
testosterone therapy has not been shown to increase cancer risk.)
7) Sex Boosts Immunity. Yes, indeed, one study of healthy young males
revealed a signficant increase in natural killer cells post-orgasm. 
Other studies have shown an increase in IgA, one of your body's automatic
weapons against colds and flus. 
CAUTION: Recent research shows that having sex more than a couple
times per week may actually regress this immunity boost.  This may be
because opioid peptides, which sex stimulates, boosts immunity in moderate doses
but actually acts as an immunosupressant at higher levels. What about the studes
that say that show a dose-dependent reduction in mortality as you increase
orgasms per week? Unfortunately, these studies have maxed out at about two
times per week and this is the first study that shows there may be a point of
diminishing returns. However, this may be a cause worth dying for, eh?
Sex May Grow Your Brain. Increased stress levels increase cortisol
and cortisol is a known hippocampus-shrinker. Researchers recently decided
to show in a study of rats that repeated sexual activity would increase stress
hormones and shrink the rats' hippocampus. And it would serve 'em right,
don't you think? Instead scientists found that
stress hormones increased for a few days, decreased to normal levels and then
something surprising happened: the rats hippocampus starting growing!
They conclused that repeated sex, for these lucky adult male rats, "stimulated the growth of
dendritic spines and dendritic architecture." C'mon - if a bunch of
rats can do it, why can't you? 
9) Sex Lowers Stress Hormones. The study above found that the lucky rats had
lowered levels of the nastiest stress hormones called glucosteroids. 
In fact, they speculated that this may be one of the primary reasons that sex
caused the brain cell growth. A number of studies have shown that immediately
after sex, cortisol actually increases. However, this study indicates that
in the medium term, the picture becomes significantly different. This may be because
an orgasm release oxytocin and oxytocin lowers cortisol. 
10) Decent Exercise. A recent study shows that the typical guy will burn about 101 calories per love making
session.  That's enough to significantly help with weight management and the researchers even noted that it achieved moderate exercise intensity.
