Will I bleed the first time I have sex?
– Cait*

Not every girl bleeds the first time. The reason why some girls do bleed the first time they have sex is because the hymen, a very thin piece of skin-like tissue that stretches partly across the opening of the vagina, breaks or tears. Some girls are born without much of a hymen, while some girls' hymens cover a large portion of the vagina's opening — it all depends on the girl.

Whether a girl bleeds also partly depends on whether the hymen is broken or torn before sex. This may occur from vigorous physical activity; tampon insertion; and masturbation and fingering. Remember to always wear a condom every time you have sex, including the first time, to protect against pregnancy and sexually transmitted diseases (STDs).
