Yes, slapping or any form of physical violence during sex without consent is considered sexual assault and is a form of physical abuse. If someone slaps you without your consent during a sexual encounter and causes injury, such as breaking your jaw, it is a severe violation of your rights and a criminal act.
Sexual activity should always be consensual, meaning that all parties involved must freely and willingly agree to participate. Any form of physical violence or coercion during sexual activity is not only illegal but also morally wrong and harmful.
If you have experienced this kind of abuse, it's crucial to prioritize your safety and well-being. Reach out to a supportive friend or family member, seek medical attention for any injuries, and consider contacting law enforcement or a local support organization for survivors of sexual assault. They can provide guidance, support, and resources to help you navigate the situation and seek justice if you choose to do so. Remember that you are not at fault, and you have the right to be treated with respect and dignity in all circumstances.
