Felix d'Eon was born in Guadalajara, Mexico, to a Mexican mother and a French father. His father passed away while Felix was still a boy, and the family (mother, two sisters, a little brother and a twin brother) moved to Pacific Palisades in Southern California. Felix demonstrated an early aptitude for art, and began drawing students, boyfriends, and other members of his swim team from life while he was in High School. His mother enrolled him in figure drawing courses at a local community college at age 15, but shortly thereafter, Felix and his brother ran away from home and spent nearly a year living on a beach in Mexico, and then in Mexico City, working as "models," drawing sidewalk portraits, and with occasional stints as kept boys. Upon returning to Pacific Palisades and graduating High School, he went to live in San Francisco, where he graduated with honors from the Academy of Art University.

In addition, Felix has spent summers, semesters taken off from school, and extended stays since college in various cities around the world, such as New Orleans (where the brothers were strippers at The Corner Pocket), New York (a job as an erotic cake decorator), Milan, Italy (a kept boy), Tennessee (Gentleman Farmer), and Buenos Aires (a flaneur). His permanent home is in San Francisco, where he lives with two lesbian roommates, a charming houseboy, an erstwhile boyfriend, occasional lovers, and two startled cats.
