ok, first of all, your bff should not be inserting anything into her pussy that isn't meant for vaginal penetration...I watched a show called 1000 ways to die, and in this one episode, this girl is masturbating with a shaved carrot...She tore her vaginal walls and bled to death...If she is that desperate, be a friend, and tell her that there are safer methods to masturbating...Go with her to an adult store, and don't be shy to ask for some assistance...They won't laugh at you or say "ew gross"...It's their job to help people, and if you are shy too, let her ask the questions...But stick to the plastic dildos, and if she is just looking to get her clitoris off, then tell her to buy a "bullet". It is a battery operated tiny oval shaped vibrator just for clitoral stimulation...So, if you don't want your friend to masturbate to death, lead her in the right direction.....
