well my friend was explaining to me what a hymen is. She claims it will pop when you do it for the first time and blood will come out but she herself is a virgin. My other friends are always telling me that when you do it for the first time your "cherry" will pop & im not exactly sure what this "cherry" is but i would like to know if it's the hymen.

I just wanna know if any kinda of liquid or discharge comes out while doing it for the first time.
