Raised religious

Hey ladies! I was raised in a very religious home as a child/young adult. I'm now in my twenties and have been dating a really awesome guy for the past few months. Things have started to move forward sexually in our relationship and because of how I was raised I've struggled with this. I love him and genuinely WANT to be with him, but in the back of my mind it still feels like I'm not doing the "right thing". Did anyone else struggle with this? How did you move forward?
