Masturbation can lead to glansitis. Although masturbation itself is not considered a bad sexual habit, unclean masturbation or long-term masturbation is likely to cause the glans to become more sensitive. This is the time to get infected by some germs, which can lead to gladiolus. When the glans is present, it can cause urethritis, retrograde infection causing prostatitis, and it may cause abnormal urination. There is also the possibility of some rash or itching of the glans. It is usually advisable to quit masturbation at this time and go to a hospital urology or male department for treatment.
