When intercourse or other forms of sexual behaviour is forced through violence, it seems quite obvious to all that rape or sexual assault has taken place. Where violence or excessive force is not a feature though, the lines become a little more blurred. The concept of sex or sexual behaviour being coerced rather than forced is considered in more depth in coercive sexual abuse.
Rather than using physical force, the abuser will frequently use coercive sexual abuse.
He will use guilt, pity, anger, moods, nagging or accusations to 'persuade' us. He does not see this as sexual abuse, but it is. Any sexual act that has been coerced is abusive.
