Is this good?

So my Girlfriend went out tonight, got a bit drunk. When she got back to her flat she told me that she grinded on a guy, but felt bad about it, she also pied of many guys.

Now, upon reading this I didn't feel any kind of negative feelings at all.

Is this a good thing? I'm thinking it means I obviously trust her 100%, which I wouldn't doubt at all.

Guys, what would your reaction be if this happened to you?
