Do all women bleed the first time they have sex?

No, not all women bleed the first time. The reason that many bleed the first time is that the hymen tears. The hymen is a soft edge protruding from the wall of the vagina that makes it a bit narrow. When the penis penetrates for the first time, the hymen can tear resulting in a small amount of bleeding. This is completely normal. If you don’t bleed, it doesn’t mean that you don’t have a hymen, it just means that it isn’t attached to your vaginal wall. All women’s bodies are slightly different.
