What Does 'Penetrate' Mean In A Sexual Way?

Sexual penetration is the act of inserting something into a bodily orifice, such as the vagina, mouth, or anus.

What’s The Difference Between Sexual Penetration And Sexual Intercourse?
Sexual intercourse usually describes the insertion of the penis into the vagina or anus. Essentially, sexual intercourse is “having sex.”

On the other hand, sexual penetration doesn’t have to involve a penis – the insertion of fingers or sex toys also counts as sexual penetration.

The actual definition of sex varies from person to person. Some people count any kind of sexual activity as sex, whereas other people reserve the term for full-on sexual intercourse. There's no right or wrong definition, though!
