Things that had not occurred to me about the internet: That the person to whom one lost one's virginity on the beach at summer camp* might track one down on facebook, after not having seen or spoken to said person in five years.

*we were counselors, not campers and of an age reasonably to be able to consent. It might also be worth mentioning that, although I am not a person of faith, it was a Church Camp, where I know for a fact lots of other people also had their first sexual experience.
