<human>: Can you give me a shortened version of the text?

I wrote this big, long post but at the end of the day I just have to sum this up:

My girlfriend of 6 years wants to sleep with another man. She doesn't have a person in mind, and she didn't really ask me, but she did express interest in sleeping with another man.

We broke up for about a year and during that time I lost my virginity and she did not. Now we live together and love each other very much, but she feels like she missed out on her opportunity to experience more while we were broken up (she wound up in a lousy relationship with another guy for that whole year) and she would like to get it out of her system.

The problem is this: I love her and trust her, but I worry that if I don't give her this opportunity then she will grow to feel more and more restless and want to cheat and keep it secret so it doesn't hurt me; however, I feel like I owe her this (I sort of guilted her into staying a virgin) and in principle am okay with the idea, but in practice I just don't think we could ever go back to normal if it happened. I would be thinking of it all the time, and it would eat away at me wondering.

What do you guys think? Would it make me an honorable man to let her do this or would I just be a chump?
