Sexuality is a big category that includes A LOT of diversity within it!
There are allosexual identities and asexual identities. There are monosexual identities, desires, and expressions (heterosexual, gay, lesbian, etc.), non-monosexual identities, desires, and expressions (bisexual, pansexual, etc.). Additionally, human experience sometimes isn’t so binary as allosexual vs asexual or monosexual vs non-monosexual. For example, someone could be asexual and biromantic.
Regardless of the identity, desire, or expression, growing up in an allosexual heterosexual world is hard when you don’t identify or feel that way! There have been many areas where it has gotten better, such as marriage equality. But sadly, that doesn’t mean that bigotry isn’t alive and well. Heterosexual privilege still impacts everyday life for gay, lesbian, and queer people who are only attracted to one sex or gender. Monosexual privilege impacts everyday life for bisexual, pansexual, or queer people who are attracted to more than one sex or gender. Allosexual privilege impacts people on the asexual and aromantic spectrums. On top of it all, people with other intersecting identities (race, ability, class, gender, etc.) have to deal with exponentially more.
Psychotherapy can help work through anger around privilege and shame around identity in order to find more authenticity to live a life full of integrity.
