If you're in your mid to late 30's, you might be interested in this.  If you're past 40, sorry, it's too late, and if you're much younger, you probably won't remember this by the time you get to your mid-thirties.

Now, we're mammals, plain and simple.  That's you over on the right, ya big stud.  And our biology works like most mammals.  The cows ovulate, the bull impregnates them.  When the bull reaches a certain age, a younger male takes over so the seed is fresh.  It's known as Natural Law and it's embedded in a mammal's genes.

And so it is with humans. That "certain age" in a human is around 40.  If your sexual activities have slowed down, your main hormone secreter, the pituitary gland, will receive the message and you will never again have the sexual potency that you once had.  In other words, you just won't be able to get it up as often.  You'll be staring down at it with some willing broad by your side saying, "What's the story, buddy?"

The good news is that you can fool your pituitary gland into thinking that you're still 'at stud', and it will continue to give you the sexual energy you've always enjoyed.  And you'll have the potential to stay this way for the rest of your life — if you can get past this critical biological period.

In other words, the body only checks once to see if the old bull's time is up, and if you can fool it into thinking you're still 'at stud' during this period, it will never ask again. Those "dirty old men" and "randy old goats" went through this period with an active sex life, and that's why they're so "active" (meaning, just like they used to be) in their later years.  And their virility is noticed, to the point that these men actually have nicknames, i.e. "randy old goats".  The reason they're singled out is because it's a relatively small group, and it's no great secret why.  By age 40, most men are bored to tears with their wives (and vice versa) and have fallen back to sex once a week.  To the pituitary gland, that's a big red flag saying, "Okay, this guy's all through."

Don't let it happen to you.
