I had a sexual experience with a woman in college one-time, copious amounts of alcohol were part of the equation. It just wasn't my thing. She was a pretty Argentine-American, blondish brown hair, green eyes...she'd always just been a friend. That night we were passed out drunk on my bed at my apartment...she hit on me and I guess I must have thought, what the fuck...
I have regrets, after the next morning we both sort of stopped checking in with one another and drifted apart. That sucked, but shit...20 years old is very young. It was awkward and we handled it poorly.
