Curious to know if a girl can loose virginty because of masterbating with pillow?
no that is virtually impossible.....Unless something is inserted into the vagina and penetrates and then breaks the hymen that is they way to lose one's virginity in the physical sence.
Only by having a real live penis in your vagina will take away your virginity. Merely breaking the hymen will not, after all, using a tampon or a Mooncup will break the hymen.
