I've been meaning to share this bit of information with my fellow men on this site and realized I could blog it. Never done the blog thing before. I always thought "blog" was the sound you made just before you started to throwing up so I've been a tad resistant.
Anyway, what I want to share is about holding the semen in. When you are with your lover and find you just slipped over the edge, or you're spanking the monkey, about to blow your big load, instead of letting it fly you can keep that precious substance in your body by doing this technique. Simply press the spot half way between your testicles and anus with three fingers, firmly. Most of the pressure on the middle finger. You will pulse like a regular ejaculation but nothing will come out and your semen will just get reabsorbed. You should find that you feel much less depleted and your energy will come back much quicker. For those that enjoy indulging in guilt afterward you may find that the self flagellation period is less enthusiastic.
This is an old Taoist technique that I have applied over the years with excellent results and cant recommend it enough. The Taoists claimed semen was a vital potent substance for the man and was best kept inside his body except for making babies. For those that say its not good to hold it in this way, I say nonsense, I trust the ancient Taoists and have never experienced any ill effects from doing it myself.
I doubt that it will happen but it would be very interesting to see a scientific study done on this to see what happens with the brain chemistry using this technique as opposed to a full ejaculation.
I still recommend obstaining from orgasm/ejaculation all together but when you do go over the edge, intentionally or not, this is a good half way measure. Give it a try.
