Yes i am lesbian

Why would a girlfriend BEG for months to put an egg in my ass (sexually), and then when i finally give in, she calls me “yolk-assed bitch” in public and even in front of my parents?

*i put my sexuality in case someone was confused about me saying my girlfriend. I know it’s practically 2018 and everyone would probably get the jest, but their might be someone who doesn’t, so i wanted to clarify.*
