For example:
* Me lavo (I wash myself) - *Present tense*
* Me lavé (I washed myself) - *Past tense*
* Me lavaré (I will wash myself) - *Future tense*
However, if the verb is in the infinitive or gerund form, the reflexive pronoun goes after the verb, attached to it with a hyphen.
For example:
* lavarse (to wash oneself) - *Infinitive*
* lavándose (washing oneself) - *Gerund*
Important notes:
* The reflexive pronoun agrees in gender and number with the subject of the verb.
* If the verb is in the imperative mood, the pronoun can be placed before or after the verb, but it is more common to place it before.
* If the verb is part of a compound tense (like the past participle), the reflexive pronoun goes before the auxiliary verb.
Examples:
* Me he lavado (I have washed myself) - *Present perfect*
* Se ha vestido (He/She/It has dressed himself/herself/itself) - *Present perfect*
* Nos vamos a duchar (We are going to shower ourselves) - *Future tense*
* Te estás peinando (You are combing your hair) - *Present progressive*
