I feel so guilty but I know I shouldn't..

I feel so guilty. When I was 15, I lost my virginity to a guy that was almost 19. He was very manipulative. He should've gone to jail for rape but they let him go. He had sex with so many girls that were younger than 15 while we were together. He tore me completely apart. He gave me so many trust issues. Now I have the best boyfriend in the world. He was a virgin before we got together and I just feel so guilty that I couldn't give him mine too. I know it's stupid but I literally lost my virginity to a rapist. I feel disgusting and I hate I couldn't give my boyfriend the same thing he gave me. He tries so hard to convince me that it doesn't bother him but it bothers me. I'm just venting.
