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.
New forms of sexual violence:
3.1 through Sexting:
Sending sexual, erotic or pornographic messages, through technological devices and platforms, without consent.
Spreading images or videos with sexual contents without consent.
Denial to use contraceptive methods:
It is a very common practice in sexual relationships when the man refuses to use any kind of contraceptive methods. It is usually combined with blackmailing or threats.
There is also the so-called “stealthing”, which is taking out the condom in the middle of the act, without the partner consent.
