In spanish it could be translated as “comportarse”

Yo me comporto Tú te comportas Ella se comporta Nosotros nos comportamos Vosotros os comportáis Ellos se comportan.

I think they are called reflexive verbs. Because they have to be conjugated with reflexive pronouns.

If not it would be.

Yo comporto Tu comportas Ella comporta …

Which sounds weird as hell. So I suppose you are right also in Spanish.
