Dear xxbelle23xx,

No, this is not true — masturbation has no effect on menstrual flow. But it can relieve menstrual cramps, and, during menstruation, masturbating to orgasm may protect against endometriosis.

It is safe and healthy for a girl to masturbate when she has her period. If a girl is using a tampon, she should remove it before insertive masturbation. Otherwise the tampon and its string could get pushed up too deep in the vagina for the girl to get it out herself.

Hope this information helps!

Take care,
