No, masturbation absolutely does not affect your ability to have children in any way. It can actually be good for your general health and especially your pelvic floor muscles.
The liquid that comes out is perfectly normal too. There is no reason to be worried or to stop masturbating. Just use clean fingers and toys to avoid infection, like the other poster said.
Anushay, read some of the health-oriented websites that talk about human sexuality (not porno sites, educationally oriented sites about the human body and sex). It is normal to masturbate. It will not interfere with your future fertility. But it is not normal if you were to (for example) be so obsessed with it that you ignore your normal daily activities to do it, or masturbate somewhere that is not private, or other more unusual behaviors. Simply masturbating at home in the privacy of your own room is neither abnormal nor dangerous. (Just be sure to wash your hands before you touch yourself, fingers have a lot of germs.) As the above poster says, if you are feeling out of control with this, see a therapist. But simply masturbating every now and then at home in your own room is not unusual.
I'm trying to make out what you are asking.... Are u saying that u masterbating?!? Im so confused by your wording but trying to understand. There are so side effects everyone feels relaxed after the release from orgasm? If u feel that you have a problem with overly masterbating then you may need professional help.
