I'll also put this here • Sex - sex assigned at birth (male female) • Gender - Identity affected by the environment and culture (what is defined as feminine or masculine) Ex; The sex of the baby is Female (sex assigned at birth based on the chromosome) but growing up with 5 older brothers made her masculine (gender expression due to the environment she lived in) : Note that it doesn't mean that if she acts masculine = she's lesbian or trans. • Gender Identity - psychological sense of one's gender (this is psychologically speaking what you think you are) • Sexual Orientation - sexual & emotional attraction to another person (what your attraction is) Ex; Luka is biologically male (sex) his dad raised him up to be tough and manly resulting in Luka being very masculine (gender) but he identifies himself as a Masculine Woman (Gender Identity) and attracted to women (sexual identity) Hope this helps, it's really not that hard to understand if you actually try to listen
