If you are asking how to delay your ejaculation, here's one way:
Masturbate, paying close attention to how your body feels just before ejaculation.
"Work backwards," noting the signals your body is giving as it approaches ejaculation.
Masturbate, but stop when you feel the signal. Wait until your penis starts to soften, then continue masturbating. Repeat until you've got the hang of it.
No, it does not hurt. There is a strange sensation which is enjoyable. The more often the boy masturbates the more enjoyable the ejaculation of semen becomes.
For us males it is pretty much of a one time shot, then we need to build-up the semen once more,before the next ejaculation. We produce about 1 teaspoon of semen for the average ejaculation. The volume of the ejaculate is reduced if the time between ejaculations has not been sufficient to replenish the seminal fluid. It certainly is possible to ejaculate several times per day, but the volume of succesive loads will be reduced. Base upon my personal experience, in order to produce full volume the body requires about 48 hours between ejaculations.
The time required to reach orgasm changes from person to person. Some women need a lot of stimulation while some require less.
Yes, it increase ejaculation time. I think it is good while you are with your girl friend but not suitable while you are with your wife.
Sperm can live up to 72 hours after ejaculation.
Just a few seconds.
Any time before the ejaculation.
No, an erection does not need to have an ejaculation under stimulation. Most boys will have many erections before giving any stimulation to it sexually.
New semen is recreated all the time, so in a day or so after the last ejaculation the amount will be restored.
Ejaculation-Dildo-
There are many common terms and euphemisms. However, in medical terminology it is called ejaculation.
The average time for a man's ejaculation (in what is best described as 'clinical' sex) is something on the order of 3-7 minutes, varying according to age, sexual experience, and other factors. However, partners may put off ejaculation/orgasm to prolong and deepen the experience.
