Is masturbation bad for women? pillow humping? etc..thanks for your help. have a great day

Mastubation: Masturbation is not necessarily harmful when practiced safely. You should follow up with appropriate safe sex education should you have the desire for other experiences.

Completely normal: It never hurts to get to know your own body. Then you'll be able to communicate to a future partner about how you like (or don't like) to be touched. Other than getting a bit sweaty, and possible friction burns from battery operated devices--it is usually quite safe.
