Is this some form of SA ?

I consented to sex with this guy but I didn’t want to do it. He asked me could we have sex and the first time he asked I didn’t answer I was uncomfortable and I was unsure to answer so then he asked again but he looked at me and I got intimidated and said yes knowing I didn’t really want to do it. I feel like it’s all my fault!!! I feel like I deserved what happened but I felt pressured about the way he looked and his tone of voice. I only agreed because he looked aggressive when he asked again.
