Idk what to do

About two years ago I was raped, I’ve been terrified to have sex ever since. I’ve been in a relationship now for almost six months and my boyfriend has been super respectful that I’m not ready. But over the past month or two he has been really kinda been pushing sex and we will get to a point and then I’ll get scared and stop him. I always feel really guilty after it and more recently he’s kinda been giving me a guilt trip afterwards. I don’t know what do to guys. I love him and I don’t wanna lose him. I’m worried if I don’t do something soon he’s gonna leave me or cheat on me.
