*trigger warning* - is this rape?

So I had sex with this guy who was 29 when I was 14 years old. Can’t remember barely any of it. I only remember bits and pieces. I was with a friend who took me to a party and that guy was there. And I remember he gave me beer and for locos (idk how to spell them or if places even sell those drinks anymore) and I don’t remember if I consented or didn’t. I only remember parts of us having sex, and that’s it.

Anyways since then I have always felt sick about it (I’m 20 now). I’ve never told anyone about it, or even talked about it with anyone. I try to not even think about it myself.

Was that rape?
