I don't know if I was "raped", what would others do in this situation?

So, I'd really like to hear other's take on this situation or what they would do:

On September 14th I unintentionally lost my virginity to my boyfriend of 9 months (at the time)

We were both naked, and he was rubbing his dick against my pussy, and it went it. I did not know it was in me, I just felt a very deep pain. I said it hurt and he said it was "probably the way he was rubbing me" and I let him continue, totally unaware of the fact we were having sex.

He later texted me about how he was surprised that I didn't bleed and I was just thinking....wait, hold up...what was going on. I was so confused but I was obviously able to figure out that we had sex.

Since then we've talked about the fact that what he did could have been considered rape once, and it was very brief. Originally both of us were saving ourselves for marriage and he said it slipped in on accident. We've been having regular sex since and I guess I've come to terms with it.

I just kinda wish I know I was losing my virginity and could have really experienced it.
