Is this rape

So i went to a friends house to party a few weeks ago, we all got really drunk and I slept in the living room ( there was 2 other boys there but on separate beds). I was speaking to one boy and I consented to giving him a blowjob( in the dark, in the living room). I was so drunk I don’t remember this but I’ve been told by the boy I gave oral too ( and his mate also made jokes to me about how I can’t remember it) that his mate came up behind me without saying anything and started to have sex with me for around 10 seconds while I was telling him to get off me and saying to stop. Was this rape? Was I raped? Also because I only just found this out now ( 10 minutes ago) I was around this same guy at a party last weekend and he locked me in a room and got on top of me, stark naked and wouldn’t get off even though I was telling him over and over to get off me, I couldn’t look at him or touch him..it resulted in me having a panic attack because the room was locked and I couldn’t get out. I went home straight after and haven’t spoke to him since. What does this mean..was I sexually assaulted? Was i raped? Was this my fault? I feel sick to my stomach, I feel dirty and disgusting..I don’t know what to do
