I used to lie about my ethnicity to get girls

I’ve never been good with women and I was desperate in high school. I’m an American and I never specified my ethnicity but I would always wear clothes like Huaraches, a durag, and a diamond chain. I would say stuff like “you ever sucked a black dick” and “you ever sucked a black nigga dick” to joke around with girls. Only one girl ever said I wasn’t black because I didn’t have a black ass and she called me out on my lie but I got mad at her and almost beat her up but I didn’t. I’m ashamed of my past and I wish I never did it.
