Is it normal that ive had sex about seven times and i havent bled from it ever?

1. Some girls are born without a hymen;

2. The hymen may tear naturally when a girl plays sports or engages in any physical activity;

3. The hymen is not always smooth but tends to be perforated and that the perforations may get bigger and cause the hymen to break once a girl menstruates;

4. The hymen can be broken by the use of tampons;

5. The hymen may be very small or very elastic so that no breakage occurs at all (some women even become pregnant while their hymens are still intact);

6. A hymen may not bleed when broken.

Although being born without one might be rare, I wouldn't know.
