A few people have been asking me about edging, so I just wanted to write about it. So what is edging? Edging is mainly achieved via masturbation but can be done with any stimulation including intercourse. Edging is when you stimulate your penis to the point of orgasm and ejaculation. At the point when the ejaculation is about to take place you stop, letting the feeling subside and then repeating the exercise over and over. Basically getting close to orgasm and ejaculation without actually letting it happen. The Science Bit As you become sexually stimulated, the sperm being held in your Epidydimis (the storage area on top of each testicle) will be drawn up through the vas deferens which are the tubes connecting your testicles. As you get closer to orgasm, the testes usually get tighter and mover closer to the body as the sperm is taken up. If stimulation continues and orgasm gets closer, the sperm is mixed with seminal fluid from the seminal vesicle and prostate gland. When ejaculation happens semen (containing sperm) is flooded into the base of the urethra and the ejaculation happens. With edging this would normally be stopped before the urethra fills with the semen. My thoughts on Edging and Semen Retention Personally I would never edge or masturbate. As you can see from above, edging removes a good proportion of your sperm from the testes and creates more semen. It puts a strain not only on your testes but also your scrotum, seminal vesicle, prostate and urethra. It can give you some abdominal pain as well as pain in your scrotum (blue balls). The semen then sits in the prostate and urethra with nowhere to go, and takes a while to be reabsorbed. On top of all this, you would probably be left horny and frustrated. Another point to make is that many men and boys that are new to edging make the mistake of not stopping at the right moment, and spilling your vital fluid leaving you feeling depressed and upset. So I would not recommend masturbation at all, and I certainly would not recommend edging. Leave your sperm where it is meant to be.
