I had sex even tho I didn’t want to

So my friend spontaneously went to these guys apartment. They said we just gonna chill and stuff and we were bored so we went. Then one guy leaves with my friend to go get some juice and stuff and leaves me with the guy at the apartment. I sit away from him and he starts asking me why I’m sitting so far and come closer. I’m a big people pleaser so it’s so hard to say no I don’t know why I can’t do it. I sat closer but I moved away again and told him I wanna lay down and the chair is too small to be next to him. Then he says you wanna chill in the bedroom. I say sure knowing his intentions. As I type this out I realize that it probably wasn’t rape since I went in with him knowing what he wanted. I laid in the bed and immediately covered up and laid down like I was resting. He gets in behind me. And lays and I’m still reluctant not wanting to do anything. He asks to kiss and we do. Like after a minute he starts getting handshake and then he pushes my head so I can suck his dick and I just did because we are already in the situation. He keeps going at it and is going hard and I move my head because he’s going too rough and I’m about to throw up but he kept sticking it in my face. So we fuck so I can get him out my mouth. And he goes on for so so long. I was completely dry at some point and it was starting to hurt. My friend starts asking me to leave cause it was getting late. And he’s still fucking me. I try to stop once and he keeps going. Then I get up again and say “I need to go” he’s like “I’m not done yet” and one more time. After a little bit I get up completely and say I need to go and put my pants back on and this time he stopped. I mean I could’ve done more to stop him so I don’t know or think that it’s rape. I did kinda initiate it and I knew all intentions. I just didn’t really want to you know?
