Sexual orientation

Sexual orientation is a series of behavior patterns centered around an attraction to a person of a particular sex. There are usually three types of orientations -- heterosexual, homosexual, and bisexual -- with asexuality (a lack of attraction toward either sex) as a possible fourth.

In mainstream Smurfs media, the Smurfs and most of the characters they interact with are heterosexual in their behaviors. However, the character of Vanity Smurf is often suspect of being homosexual due to his effeminate behaviors despite showing more interest in himself than in anyone else as a romantic partner.
