Scared to have sex

I am 18 and I have had sex with a few different people. I am now in a new relationship it’s been about 3 months. He isn’t a virgin either. I have had some issues with sexual abuse in the past. Two of my ex’s had sex with me for the first time while I was very drunk. Also when I lost my virginity I was raped. I was also raped a second time by another guy after that. My boyfriend now is so respectful and a true gentleman. I have never been with anyone who treats me as well as he does and so I feel nervous around him because the situation is different. I am worried that he will think I dont like him or something due to the fact we haven’t had sex yet and have been dating for a bit. I don’t know how to get over this it’s very hard and now I feel like I’m just making myself more anxious by thinking that I should sleep with him. I have told him all of this and he was way understanding and respectful so this is not coming from his reaction at all its all me and how I’m thinking about it. I also feel myself not really caring to have sex and I’m not sure if something is wrong with me or it’s just emotional stuff I have to get over and learn to trust people again.
