When my interest started

Thinking back, I can recall that my desire to be cucked started immediately when I lost my virginity, and first had sex with my girlfriend.  One time I was at her house with my friend.  I remember that at that moment I had a desire for both of us to take turns with her.  The desire to share her sexually was overwhelming.  Since then I've often thought about where my desire to be a cuck came from.  Very recently I remembered that one of my earliest memories was sexual arousal by Kenny Roger's song Coward of the County.  The lines that specifically aroused my extremely young 7-8 year old mind were about Becky being had by three men.  Even though the song was about rape, I was very taken with the idea of this man's wife having been had by multiple other men.  I also remember being sexually aroused at that same age (7 years old) by seeing a girl that I liked, place her foot between the legs of, and press it against the crotch of another boy. I guess it’s clear that even then I could see my beta-male role being on display and providing me sexual arousal, even at a very early age.
