Some women will bleed after having sex for the first time, while others will not. Both are perfectly normal. A woman may bleed when she has penetrative sex for the first time because of her hymen stretching or tearing. The hymen is a thin piece of skin that partially covers the entrance to the vagina.

How much do you bleed when you break your hymen?

It is normal for some women to bleed the first time they have vaginal intercourse but at the same time some women don't bleed at all, and that's normal too. The bleeding is caused from the hymen stretching and usually it is just a small amount of bright red blood.

How can I check my hymen is broken or not?

Your hymen does not completely cover your vaginal opening – a hole is normal. When you have sex, your hymen does not 'break or pop' – it stretches, which may cause a small tear. You cannot tell by looking at a hymen whether sex has occurred (consensual or non-consensual).
