Wat can masturbation mete out?

1 of my friends "says" she masturbates 4-5 times a week. i am just curious as 2 wat this could do 2 her.
oh and she is merely 13yrs old okay wat i think is different from adjectives other advices u got but dont forget that one should be carefull satisfactory about hygine if not using all sorts of things instrument and toys can any cause an infection or really young amature girls can even hurt them selves! so should be a bit slow and painstaking while exploring ones body at such an early age
Nothing.. lately pleasure.
