This procedure would place an artificial one way pressure valve inline with the vasa deferentia. Connected to the testicles and also the input to the valve is an artificial duct that connects to a meatus constructed in the small of the back. To ejaculate normally (with sperm) simply place your finger over the hole on your back force the sperm past the valve and down the rest of the plumbing.

       Bone.(pardon the pun) Guys have a hard enough time with successfully using the "pull out" method. Now you want them to pull out AND put their finger over the urethra? By that time they would have already pulled out anyhow.

       The long channel that carries the sperm is kept open and free of infections by periodically flushing it with a sterile secreted fluid.   

       You will have to arrange to do some of that with your blowhole, too.

       Au contraire. Wiki citations are often less credible than a given grandad, when followed to their source.
