Meanwhile, according to a study1 from European Urology, men who ejaculate at least 21 or more times per month are 50% less likely to develop prostate cancer. So, frequent masturbation can reduce health risks as well.
The first ejaculation in males often occurs about 12 months after the onset of puberty, generally through masturbation or nocturnal emission (wet dreams). This first semen volume is small. The typical ejaculation over the following three months produces less than 1 ml of semen. The semen produced during early puberty is also typically clear. After ejaculation this early semen remains jellylike and, unlike semen from mature males, fails to liquefy. A summary of semen development is shown in Table 1.
Although uncommon, some men can achieve ejaculations during masturbation without any manual stimulation. Such men usually do it by tensing and flexing their abdominal and buttocks muscles along with vigorous fantasising. Others may do it by relaxing the area around the penis, which may result in harder erections especially when hyperaroused.
Users simply insert their erect or semi-erect penis into the opening (or orifice) at the top of the device to begin enjoying customizable hands free male masturbation during a completely manual or fully automatic session.
