<human>: So to summarize: we're young, we haven't been dating long, but we're strongly in love. I've had past relationships before - no one in the world has ever made me happier. I feel like I've become a better person, and I feel like she's truly the right person for me. She's also had past relationships before, and she's never felt happier or more excited. 

She's bisexual. Her past relationships were with other women. As a result, she's unfamiliar with male-female penetrative sex. And the fact that I've done it with someone else hurts her a lot. 

She is insecure about the whole concept. The thought that I even did it with someone before her makes her uncomfortable and sad. She doesn't know how to handle it. She admits it herself that she's insecure, and she understands that it's her problem, her issue, her own insecurity, and she's the only one who can help it. She understands that it's not my fault, and there's nothing I can do about it, and the past cannot be changed. She tries to forgive it, she tries to understand that the past does not matter. 

But nonetheless, it's hard for her. She tries to look past it, but it comes back to her and hits her. It snowballs up inside her and eats her up. I can literally see her emotions turn from happiness and excitement to sadness and discomfort. 

We're very open with each other. We're very truthful and communicative about our feelings, so all of this has been discussed - in great length. But it still hurts her. We have only been together for 2 months. So I know that after some time together, she will slowly grow to accept the past. I'm willing - more than willing - to put in the time - even years - to help her through this. 

But I can really see how much it affects her. This is literally the biggest problem in our relationship, and I know that it's gonna take a lot to get through this. 

Is there anything you think that I can do, say, or anything that she should know, that can help this situation?

Can you give me a shortened version of the text?
