I was in a relationship with a guy who would”joke” and mock all my beliefs in feminism, gay and trans rights etc. He’d tell me he was definitely right and went so far as to tell me that I had to agree with him because he is a man and I am a woman and women should listen and submit to mens wishes.
He would pressure me into sex and if I said no my reason had to be good enough.
He would joke about hurting me. he’d wrestle me and tell me that I was weak and couldn’t fight my way out or he pull out a knife and pretend to threaten me.
He would fight with me about wanting to sleep with other women or “side hoes”, he used shitty sexist language all the time.
He broke up with me and told me he never wanted to see me again, I got black out drunk at a friends birthday when he wasn’t speaking with me and he took me to his house (after I threw up on the bus) and raped me when I while I was unconscious.

Sexism starts small and gets big. It’s easier than you think to be manipulated by someone you love, I was 17/18.
