I liken the concepts of semen retention and male chastity to male libido boost/block. Let me explain…
[Note: I know there is a parallel concept for females but I am only addressing male libido here.]

Why do semen retention and male chastity seem to go hand-in-hand? I thought about it and came up with the “simple” concept of libido boost/block. What do I mean by this? The male libido is essentially the male sex drive. It is the feeling that compels us to perform our “masculine only” duty (forgive the directness) of ejaculating and impregnating a willing female. It really is that simple. Anything that can boost this libido is beneficial for our well-being and our sense of purpose. It is what keeps us males in a state of sexual “readiness”. Hence, male libido boost. [We as males have a collective libido that binds us together, but I’ll address that concept in a future post].
Now, bring-in the concept of male chastity. This is a male-blocking tool (again, forgive the directness) that prevents ejaculation by whatever means it is achieved: abstinence, locked cock cage, chastity “cup” or any other method to prevent the male from ejaculating. Hence, male libido block.
There, we have it! Male libido boost and male libido block. Two simple concepts that lie at extreme opposites. That is what makes this potent combination of semen retention and male chastity so intriguing and so appealing! Now here is a real-world example: you are very hungry and are invited to a wonderful buffet feast. But you are outside the room and the glass doors are locked! You see the delicious food but can’t get in! You get frustrated and bang on the door! But nobody pays any attention to you! Sound familiar? See the connection with sexual chastity?

Now, the tricky part. Male libido boost can be achieved through male libido block (i.e., male semen retention and male chastity). So these two concepts are intertwined. (Of course, other means can be used to boost male libido. For example, Viagra, Cialis and the like. Also, some foods are known to boost libido). Need another real-world example? Take a garden hose and put your thumb over the end. Now, turn the water on moderately fast. How long can you keep the water from coming out? See the connection with your ejaculation?

So there you have it. This is why male semen retention and male chastity are usually “paired”. One complements the other. It has come full-circle!
