lots of things can,

No they cannot tell if you have sex or if you masturbate. Even sports can tear your hymen so stop worrying.

No, they can't. LOL



Masturbation does not break your hymen. Only a man can do that.

It is difficult to ask questions like these because of the embarassment level. But you're helping someone else who felt to shy to ask but wanted to know the same thing. I hope I can answer your question and set your fears at ease.

A gynecologist cannot tell if you masturbate because there is no proof left behind by the act itself or the orgasm. Any physical proof that can be determined by the doctor is associated to breaking the hymen (aka 'popping your cherry') and would happen as a result of sexual activity or even a sport activity. There have been some cases of girls who ride horses having their hymen broken by just riding the horse. It can happen different methods because women are all different. Some are more sensitive than others and what can break one woman's hymen may not influence another girls. The only technique masturbating could break the hymen is if there were some type of device involved, like a vibrator. The force of using this device deep ample during masturbation could possibly break the hymen as done during intercourse.

I hope this helps answer your questions and gives you a better understanding. I just hope I was able to help.
