Does masturbation cause any damage to hymen layer in female ? how should i prove my partner i am a virgin? is masturbation equals to sex with some one

See answer: Masturbation by stimulation of the clitoris will not damage the hymen. While the presence of an intact hymen is the most reliable indication of virginity, the absence of a hymen does not prove a female is not a virgin for a variety of possible reasons. Masturbation vs sex with a partner are similar (??identical) physiologically but different emotional and physical experiences.
