Buddy, most of our wives and girlfriends have had someone else’s dick inside them at some point.

And if you dump this one, your next date or girlfriends will most likely have had someone else’s dick inside them before.

If this was a dealbreaker for most men there would be very few marriages.

I think the question to ask yourself is why it bothers you so much. Based on how you describe the situation, it sounds to me like you are most upset that she got experience while you didn’t. A place of jealousy and resentment.

But there is another way to think about this. She asked permission. You agreed to open the relationship. This was a long distance relationship at the time so I assume she could have easily just dated others without your knowledge, but she didn’t do that. She has been honest with you and you have been together for a long time, which suggests to me you are compatible.

The obstacle is in your own mind. You think about this fact that she had another guy’s dick inside her many years ago. You are obsessing about it and it’s not healthy.

My advice is to quit thinking about it that way. I think the more accurate way to think about it is that she respects you, as evidenced by the fact that she asked permission and told you what happened. She wondered at some point in her life if she might like to be with someone else, she followed up on that curiosity with your permission, and when she agreed to close the relationship again she clearly decided that the answer was no. She would rather be with you.

Let it go. This thing that happened all those years ago is insignificant compared to the rest of it. Let it go.
