There are many bizarre claims about masturbation, for example that it causes blindness, insanity, acne and even hair growth.
We sort fact from myth and answer your questions on what is arguably one of the most commonly practised sexual activities on the planet.
There is usually about 5ml of liquid, but there may be more, especially if a man hasn't ejaculated for some time.
Women can also ejaculate fluid, but this is far less common than for men. For the record, masturbating doesn't cause blindness, insanity, or acne and won't make hair grow on your palms.
