Let’s see a classification based on different axes.
1.1 With physical contact:
Caresses, masturbation, touching, all forms of non consented contact, and violation (with the penis, fingers or objects).
1.2 Without physical contact:
Voyeurism, indecent exposure, sexual pictures, forcing to watch porn material, indecent proposals, lascivious looks, obscene words or gestures, sexist insults.
2.1 Intimate relationships:
The perpetrator has an intimate relationship with the victim, either in marriage or while dating.
2.2 Non-intimate relationships:
The perpetrator is not the victim’s partner. He can be a stranger or, more frequently, someone known by the victim, even from her closer circle.
