Im 13 and ive been told about master bething before but idontknow what to do

Hi, if you masturbate when your alone to start with is best then your know if your moan or make a noise while you do :-)
What I would advise you do is start by exploring your whole body and find out what feels good, if you would like to know more just ask an I'll be happy to guide you :-)

Depending on what sex you are you can either finger yourself or if youre a guy you can start by rubbing penis. Either way, make sure you're alone if you do moan, because if you moan and people are there thats bad. Good luck!
