Is that assault

A few years ago, I met a guy on tinder, and we had met on multiple occasions.

The first occasion, I went to his house, and we watched a movie which led to basic foreplay but no sex.

The second time, (I was a virgin) I went over and I said yes to sex, but then when I realized how much it hurt, I said no and to stop because the pain was too much. Then he just put it back in without me being ready and after saying no saying he’d “go slow”

I started to feel something somewhat good but I couldn’t wrap my head around the fact that my consent was retracted for a minute.

My friend says I was assaulted but idk

I went back another time because I thought I really liked him and he liked me but I felt horrible even going back because I was stupid.

Please no judgement either cause I’m already feeling disrespect and sadness that I did that.
