Thats great news!
When you cum, you lose some energy, so if you keep your cum, you can use this energy for other things, like... well, I dont know your life, but whatever you want to focus on more then you used to. Say as a business man, you can put this energy now into your business and making it better, or if you are an artist, you can put this energy into making something more amazing then usual. I personally love cum and dont like any clients telling me they are doing the whole tantric thing so I wont get their cum
However, if they are not on my bed telling me this, then I think its a lovely diciplined thing to point this "life energy" in another direction then out the head of your penis
