Well, cheating is subjective. If your bf went to Vegas and a girl asked him to use his mouth to make her cum and he did, if he got himself into the same situation, would you tolerate it?

If I was your BF my first question would be, "is this woman reliable?" "Can I depend on this person?" "Can I trust this person when my back is turned?"

Somehow, it is much worse that you didn't want to cheat but you still did it. You couldn't handle yourself. Don't tell your BF. Use this as a learning experience. Make some lifestyle changes. It's time to grow up, don't you think?
