Sex Degrees Of Separation

I've been seeing this fantastic guy, "Eric," for three months, and we're starting to feel like a couple. But a year ago, before we met, I made out with a friend of his at a party. I don't want Eric to find out and think I hid anything from him. How should I go about telling him?

What barely happened in Vegas should also stay in Vegas. Yes, you and your boyfriend's friend had that special sort of attraction that leads two people to leave a party and never bother seeing each other again. Assuming there's no danger you'd run off with his friend, running off at the mouth would just give your boyfriend an icky visual to replay in his head and probably an icky feeling to go with it whenever you and his friend are in the same room. It's also unlikely that anybody would disclose this to your boyfriend, and even if they did, what would you be guilty of, pre-cheating on him? ("A year ago, my third eye was acting up, and I failed to foresee meeting you before I got a little drunk and made out with somebody you knew.") In general, it's best to avoid offering anyone details from your sex life unless they are your gynecologist or could catch something from you that would lead to a visit from a guy in a beekeeper suit from the CDC.
