Not all of them. Being sexually assaulted is a complex web of emotions which include shame, fear, and social anxiety. So much of it does go unreported, and may never be.
You know...once a feminist on YT said that women have the right to consider a sexual act rape, even after the intercourse.
Meaning: even if they gave their consent at the beginning of the act, during and at the end, they could reconsider and change their mind, afterwards...on the following day.
This is utterly disgusting and horrific.
